A new poll shows that just 26 percent of Americans support Obamacare, but at the same time only 13 percent think the law will be completely repealed. 
 
 The Associated Press-Gfk survey was completed before the White House announced this week that it had signed up 6 million people for private health plans through the state and federal exchanges under the Affordable Care Act. 
 
 The poll showed that 7 in 10 American believe the law will stay on the books with some changes. 
 
 The AP noted that support for the law has dropped 13 points since 2010, when 39 percent favored the law. Opposition also has dipped 7 percentage points from 2010, when it stood at 43 percent. The number of people on the fence, the AP reported, has tripled from 10 percent to 30 percent. 
 
 The limited support for the law is similar to what the poll found in January and December when it stood at 27 percent. 
 
 Republicans hope that the public opposition to the law will help them defend their House majority and pick up the six net seats they need to flip control of the Senate in the November midterm elections.

 The poll was conducted between March 20-24, and it involved online interviews with 1,012 adults. The margin of error is plus or minus 3.4 percentage points. ||||| Majority have consistently aligned with Democratic Party since 2006 
 
 PRINCETON, NJ -- Young adults -- those between the ages of 18 and 29 -- have typically aligned themselves with the Democratic Party, but they have become substantially more likely to do so since 2006. 
 
 From 1993 to 2003, 47% of 18- to 29-year-olds, on average, identified as Democrats or said they were independents but leaned to the Democratic Party, while 42% were Republicans or Republican leaners. That time span included two years in which young adults tilted Republican, 1994 and 1995, when Republicans won control of Congress. Since 2006, the average gap in favor of the Democratic Party among young adults has been 18 percentage points, 54% to 36%. 
 
 This Democratic movement among the young has come at a time when senior citizens have become more Republican. The broader U.S. population has shown more variability in its party preferences in recent years, shifting Democratic from 2005 to 2008, moving back toward the Republican Party from 2009 to 2011, and showing modest Democratic preferences in the last two years. 
 
 Younger Americans Now More Racially Diverse 
 
 A major reason young adults are increasingly likely to prefer the Democratic Party is that today's young adults are more racially and ethnically diverse than young adults of the past. U.S. political preferences are sharply divided by race, with nonwhite Americans of all ages overwhelmingly identifying as Democrats or leaning Democratic. 
 
 Gallup estimates that 54% of 18- to 29-year-olds are non-Hispanic white and 45% nonwhite, compared with 71% non-Hispanic white and 29% nonwhite in 1995, the first full year Gallup measured Hispanic ethnicity. 
 
 In 2013, 62% of nonwhite Americans between the ages of 18 and 29 were Democrats or Democratic leaners, while 25% were Republicans or Republican leaners. That 37-point Democratic advantage, though sizable, is slightly lower than the average 42-point advantage from 1995 through 2013. 
 
 But young adults are not more Democratic solely because they are more racially diverse. In recent years, young white adults, who previously aligned more with the Republican Party, have shifted Democratic. From 1995 to 2005, young whites consistently identified as or leaned Republican rather than Democratic, by an average of eight points. Since 2006, whites aged 18 to 29 have shown at least a slight Democratic preference in all but one year, with an average advantage of three points. 
 
 Young whites first shifted to a pro-Democratic position in 2006, perhaps because of frustration with George W. Bush and his policies. Barack Obama's presidential campaign also may have attracted younger whites, given the candidate's relative youth, particularly since Republicans nominated the much older John McCain as their presidential candidate. Young whites are not as high on the Democratic Party now as they were in 2008, but they remain more likely to prefer it to the Republican Party. 
 
 Implications 
 
 Recent decades have brought significant shifts in Americans' political allegiances, in the short term and the long term. While young adults have generally been more likely to align themselves with the Democratic Party than the Republican Party, they are now much more solidly Democratic than prior generations of young adults. 
 
 To a large extent, this reflects the increasing racial and ethnic diversity of the U.S. population, particularly among the youngest generations of Americans. And that growing diversity creates challenges for the Republican Party, given nonwhites' consistent and strong support for the Democratic Party. To some degree, Republicans have been able to offset the growing diversity and win elections by increasing their support among Americans aged 30 and older, particularly white senior citizens. But the GOP may find itself in an increasingly weak position against the Democrats unless it can broaden its appeal to younger and nonwhite Americans.
– Young voters have almost always leaned Democrat, but that trend has intensified drastically since 2006, according to a new Gallup report. From 1993 to 2003, an average of 47% of 18-to-29-year-olds identified as Democrats or independents who leaned Democrat, compared to 42% who identified or leaned Republican; in 1994 and 1995 Republicans even briefly had an edge. But since 2006 that gap has exploded, and is now at 54% to 36%. Partially that lines up with an increase in racial diversity. Today 45% of young people aren't white, up from 29% in 1995, and non-white Americans lean heavily Democratic across all age groups. But even young white people now lean Democratic, where they used to lean Republican. But not all the polls out today are nearly as encouraging for Democrats. Others include: Support for ObamaCare has dropped to 26% in a new AP/Gfk poll, the Washington Times reports. Support for the law has dropped 13 points since 2010, although opposition for the law has also decreased, dropping 7 points. The Washington Post notes that the same poll showed that 59% of Americans now disapprove of Barack Obama, a new high. His approval rating stands at 41%, his second-lowest ever.
