Today the Senate will make history, swearing in a record-breaking 20 female senators -- four Republicans and 16 Democrats -- in office. 
 
 As the 113th Congress is sworn in today on Capitol Hill, ABC "World News" anchor Diane Sawyer has an exclusive joint interview with the historic class of female senators. 
 
 Diane Sawyer's complete interview will air on "World News" and "Nightline" tonight. 
 
 "I can't tell you the joy that I feel in my heart to look at these 20 gifted and talented women from two different parties, different zip codes to fill this room," Sen. Barbara Mikulksi, D-Md., said while surrounded by the group of women senators. "In all of American history only 16 women had served. Now there are 20 of us." 
 
 Senator-elect Deb Fischer, R-Neb., today becomes the first women to be elected as a senator in Nebraska. 
 
 "It was an historic election," Fischer said, "But what was really fun about it were the number of mothers and fathers who brought their daughters up to me during the campaign and said, "Can we get a picture? Can we get a picture?' Because people realize it and -- things do change, things do change." 
 
 The women senators all agree that women will be getting things done in this new Congress, a sign of optimism felt for the new Congress, after the bruising battles of the 112th Congress. 
 
 "We're in force and we're in leadership positions, but it's not just the position that we hold. I can tell you this is a can-do crowd," Mikulski said of both Democrats and Republican senators in the room. "We are today ready to be a force in American politics." 
 
 And while the number of women in the Senate today makes history, many of the women agreed that they want to keep fighting to boost those numbers. 
 
 Sen. Barbara Boxer, D-Calif., said that women are still "underrepresented" in the Senate. 
 
 "I think that until we get to 50, we still have to fight because it's still a problem," Boxer said. "I think this class as you look around, Republicans and Democrats. ... I think that because of this new class and the caliber of the people coming and the quality of the people coming, I think that hopefully in my lifetime -- and I really do hope and pray this is the case -- we will see 50 percent. " 
 
 No Sorority Here, Even With the Will to Work Together 
 
 The cooperation does not make them a "sorority," Sen. Dianne Feinstein, D-Calif., says. There are real differences in ideology and personality and they don't want their gender to define them as senators. 
 
 But the women also admit that they believe having more women in the room would help in fierce negotiations, compromise and legislating on Capitol Hill, traits they say do not come as naturally to their male colleagues in the Senate. That sentiment enjoys bipartisan support among the women of the Senate. 
 
 "What I find is with all due deference to our male colleagues, that women's styles tend to be more collaborative," Sen. Susan Collins, R-Maine, said. 
 
 Sen. Claire McCaskill, D-Mo., said by nature women are "less confrontational." Sen-elect Mazie Hirono, D-Hawaii, says that women are "problem solvers." 
 
 Sen. Amy Klobuchar, D-Minn., says that women have a camaraderie which helps in relationships that are key to negotiations on Capitol Hill, something she says comes natural to women more than men. 
 
 "I think there's just a lot of collaboration between the women senators and... advice and really standing up for each other that you don't always see with the men," she said. 
 
 Feinstein said that women are more effective working in Congress because of these traits that they bring to the table. 
 
 "We're less on testosterone," Feinstein said. "We don't have that need to always be confrontational. And I think we're problem solvers, and I think that's what this country needs." 
 
 Sen. Lisa Murkowski, R-Alaska, agreed. 
 
 "Maybe it is the testosterone that you speak to, Dianne, or the ego that is attached there. But I look at what I have been asked to do by the people of Alaska, and it's pretty serious stuff. And it's not the title, but it's the responsibility that comes with the service that I think makes a difference," Murkowski said. 
 
 In the combative halls of Congress, McCaskill argued that for all these reasons women can get beyond "team mentality" of Democrats vs. Republicans and work towards a better goal. 
 
 "Having us in the room... not only do we want to work in a bipartisan way, we do it," McCaskill said. "We actually work together, Republicans and Democrats, and women- try to look at solving the problem rather than just going political points." 
 
 But the women agree that just because their natural tendencies lean toward problem solving, camaraderie and compromise it does not mean they don't fight for what they believe in, which at times can be markedly different from their female counterpart on the other side of the aisle. 
 
 "That doesn't mean that we think alike, and it doesn't mean that we don't span the ideological spectrum," Collins said. "I always push back the idea that there are women's issues. Because every issue from war to taxes to education affect women in this country. And that's why the point of having women be represented on all committees and leading many of them is so important." 
 
 Reproductive rights 
 
 One of those ideological differences that often divides the two parties, and oftentimes women as well, is the issue of reproductive rights. 
 
 Last year the issue took a center stage in the 2012 presidential campaign as well as in races across the country during the congressional elections as a highly polarized and emotionally charged topic. 
 
 The senators showed there is disagreement among them on abortion, reproductive health decisions and even disagreement as to what leadership role women and Congress should play in the debates ahead. 
 
 "I'm pro-choice," Collins said. "But I think those issues should be settled and should not be the main focus of debate. To me those issues, Roe v. Wade, is settled law and I don't know why we would want to keep bringing those issues up. I think we should be focusing like a laser on job creation, the economy, health care, education, foreign policy, national security. Those issues to me are settled." 
 
 Sen-elect Elizabeth Warren, D-Mass., disagreed, saying Republicans put those issues onto the Congressional radar screen. 
 
 "I don't think they are entirely settled," Warren said, "I have to say I was really shocked that those are powerful issues in 2012. I would like to think those things are settled. But they were forced forward as issues by people who thought that women should not have that kind of access. And boy, if that's the case, then we better stand up and we better speak out." 
 
 Can Women Fix Washington's Dysfunction? 
 
 The 112th Congress may be best known for long-drawn out fights, fierce partisanship and little to show legislatively for the year. 
 
 The senators argue, at the dawn of a new Congress, that having more women in leadership positions and in the ranks as members will help improve the outlook for a more productive year. 
 
 Sen. Maria Cantwell, D-Wash., says that women "leave their ego at the door and "more natural consensus builders." She said because of those traits women should be elected into more positions in Congress. 
 
 "If the major issue of our era right now is the stalemate of Congress, then the message to the American people should be elect more consensus builders to get the job done," Cantwell said. 
 
 Sen. Kirsten Gillibrand, D-N.Y., said that if Washington is ever going to be fixed she believes "it's women who are going to lead the way." 
 
 The senator says she's spoken to President Obama about this very issue, mentioning to the president that the women have a habit of meeting regularly on a bipartisan basis for dinner. The president, she said, plans on hosting the women of the Senate at the White House soon. 
 
 "When I saw President Obama a few weeks ago I told him about our quarterly dinners and I said, 'Mr. President, if you want to see bipartisanship in Washington invited the women senators to help you get it done.' And he loved the idea and he plans to invite us to the White House." 
 
 Predictions for a Female President 
 
 Among the senators there was unanimity in predicting, and hoping, that there will be a female president soon, perhaps as early as 2016. 
 
 Sen. Patty Murray, D-Wash., said here too there is a key difference between how men and women express their personal and political ambitions. 
 
 "I think the thing is, is that every man wakes up in the morning and looks in the mirror and says, 'I could be president.' I think every woman looks in the mirror and says, 'What can I get done for my country today?' " 
 
 Feinstein jokingly corrected her noting that a few times she's toyed with the idea in the midst of a particularly bad episode of Washington gridlock. 
 
 "Well, you may think it from time to time," Feinstein said smiling at the prospect. "Usually when you're very frustrated you think... 'If I were president I could get this done.'" 
 
 Sen. Kelly Ayotte, R-N.H., shared a story about her 8-year-old daughter, Kate, who came home one day and told her mother that she didn't want her to run for president because she herself wanted to be the first female president. 
 
 "Well she better call Hillary [Clinton]," Boxer quipped of their former colleague in the Senate, widely believed to have a shot at the White House should she run in 2016. 
 
 "Did you break the news to her we're not waiting that long?" McCaskill asked with a laugh. 
 
 Ayotte smiling said she didn't want to break the news to her daughter that there potentially could be a female president before her daughter is of age. She said she told her: "Listen, your mom's going to campaign across the country for you." ||||| This dysfunctional Congress has often looked like an unruly schoolyard, with cool kids, nerds, bullies and outcasts all vying for their own piece of turf. 
 
 And while we wouldn’t want to diminish the massive, consequential issues that Congress is struggling with by comparing the hardworking lawmakers to schoolkids, let’s be honest, it often looks like one big popularity contest.

 reset Reps.-elect outlook positive POLITICO LIVE: 113th Congress comes to Washington 
 
 With a slate of 84 House rookies being sworn in on Thursday, the freshmen are already angling for their spots in the pecking order. POLITICO has jumped ahead with predictions for freshmen superlatives for the incoming 113th Congress, identifying the people whose names you’ll see in the headlines in the coming year. 
 
 Most likely to succeed 
 
 Tom Cotton (R-Ark.): Thirty-five-year-old political newcomer Tom Cotton is already lauded as one of the GOP’s fastest-rising stars. Cotton handily put the Arkansas district of retiring Democrat Rep. Mike Ross into Republican hands, has an impressive résumé and a growing list of fans on the Hill. The 6-foot-5 Harvard Law graduate left a law practice in 2004 to enlist in the Army, served in Iraq and Afghanistan and won a Bronze Star. Between tours, he was part of the Old Guard at Arlington National Cemetery. During his campaign, Cotton was cheered by everyone from Sen. John McCain to the fiscally conservative Club for Growth to Mike Huckabee. Cotton’s widespread appeal across GOP circles already has many buzzing he’ll quickly move up the ranks in the House. Recently, Cotton penned an op-ed for The Wall Street Journal from a “soldier’s eye view” slamming the could-be nomination of former Sen. Chuck Hagel for secretary of defense, and he’s been one of the loudest voices against the sequester — a signal he’s more than ready to be his party’s voice on the Pentagon and defense spending. 
 
 Raul Ruiz (D-Calif.): Getting three degrees from Harvard and becoming a successful emergency room doctor just wasn’t enough for Raul Ruiz. In fact, the average three-day workweek of the Hill will probably seem like a vacation for Ruiz. Before he ran for Congress, the doctor was running a mentorship program, working in an ER, opening health clinics and running health education seminars for poorer communities. Ruiz, who unseated longtime Rep. Mary Bono Mack, figures to bring the same nonstop work ethic to Capitol Hill. Ruiz told POLITICO in November he has plans to work with everyone to get things done. “I’m a doctor, we work in teams,” he said. “I’m very committed to problem solving.” Expect him to be an outspoken and important voice for the party on immigration issues.
– The fiscal cliff deal was the last hurrah for the 112th Congress. Now a freshly elected class is coming to Washington, with more than 90 new faces gracing Capitol Hill. Here are some of the notable names and facts you'll want to know: The Rising Star: Politico sees big things in store for freshman GOP Rep. Tom Cotton, who left his law practice in 2004 to fight in Iraq and Afghanistan. He's already earned endorsements from such disparate GOP figures as John McCain, Mike Huckabee, and the Club for Growth. The Workaholic: Before coming to Congress, freshman Democrat Raul Ruiz was working as an ER doctor, running a mentorship program, opening health clinics, and running education seminars in poor areas. And he sounds ready to bring that level of dedication to Washington. "I'm a doctor, we work in teams," he says. "I'm very committed to problem solving." The Class President: Republican Luke Messer has been named president of the freshmen, and sounds like he's already got a handle on things, reports the Hill. "At our first meeting I established a rule where … no one could talk more than two minutes," he said on TV recently, "so our first meeting took 18 minutes, and everybody was very happy." The Inspiration: Expect veteran and double-amputee Tammy Duckworth to be a favorite of the Democratic leadership. She's already proven herself a prodigious fundraiser, given a well-received speech at the DNC, and landed a spot on the Armed Services Committee. The Pro: She may be a newcomer to Congress, but Ann Wagner has loads of experience, having chaired or co-chaired the Missouri Republican party, the RNC, and Roy Blunt's 2010 Senate campaign. John Boehner has already selected her to deliver the weekly GOP address. The Loudmouth: Alan Grayson is back, everybody. The Wrangler: There's a decent bet you'll see Ted Yoho on cable news. A large-animal veterinarian by trade, Yoho at one point ran an ad featuring mud-spattered politicians wrestling with and eating alongside pigs. Maybe he can hang out with fellow Republican Kerry Bentivolio, a reindeer farmer from Michigan. The Empty Seats: This Congress will be notable in part for the colorful personalities that are departing: Barney Frank, Ron Paul, and Dennis Kucinich will all be gone. The Familiar Names: There will once again be a Kennedy on Capitol Hill, as Joseph Kennedy returns to fill Frank's seat. Joaquin Castro, meanwhile, brings a familiar face—he's the twin brother of DNC keynote speaker Julian Castro. The Ladies: ABC News reports that the Senate will, as of today, be comprised of a record-setting 20 females.
