2001, while he was the Senate Majority Leader, Daschle's office received a letter containing anthrax, becoming a target of the 2001 anthrax attacks. Some of his staffers were confirmed to have been exposed, as well as several of Senator Russ Feingold's staffers and Capitol police officers. His suite at the Hart Senate Office Building was the focus of an intensive cleanup led by the Environmental Protection Agency. Views on abortion Daschle has a mixed voting record on abortion-related issues, which led the pro-choice organization NARAL to give him a 50% vote rating. In 1999 and 2003, Daschle voted in favor of the ban on partial-birth abortion, and supported legislation making it a crime to harm an unborn child when someone attacks a pregnant woman. (Investigators into the 2001 anthrax attacks, which included Senator Daschle's Capitol Hill office, suspect that alleged anthrax mailer Bruce Ivins may have chosen to target Daschle over his views on abortion, although Ivins's lawyer disputed this alleged motive.) In 2003, Roman Catholic Bishop Robert Carlson reportedly wrote to Daschle, criticizing his stance on abortion as conflicting with Roman Catholic teaching, and stating that Daschle should no longer identify himself as a Catholic. 2004 Senate election In the 2004 Senate election, John Thune defeated Daschle by 4,508 votes, 50.6% to 49.4%. It was the first time that a Senate party leader had lost a bid for reelection since 1952, when Barry Goldwater defeated Ernest McFarland in Arizona. Senate Majority Leader Bill Frist visited South Dakota to campaign for Thune, breaking an unwritten tradition that a leader of one party would not actively campaign for the defeat of the other. Throughout the campaign, Thune, along with Frist, President George W. Bush, and Vice President Cheney, frequently accused Daschle of being the "chief obstructionist" of Bush's agenda and charged him with using filibusters to unjustly block confirmation of several of Bush's nominees. The Republican candidate also drove home his strong support for the war. In a nationally televised debate on NBC's Meet the Press, Thune accused Daschle of "emboldening the enemy" in his skepticism of the Iraq War. When the race began in early 2004, Daschle led by 7% in January and February. By May, his lead was just 2% and summer polls showed a varying number of trends: Daschle or Thune led by no more than 2%, but some polls showed a tie. Throughout September, Daschle led Thune
