In the lame duck session of the 111th Congress, McCain voted for the compromise Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010, but against the DREAM Act (which he had once sponsored) and the New START Treaty. Most prominently, he continued to lead the eventually losing fight against "Don't ask, don't tell" repeal. In his opposition, he sometimes fell into anger or hostility on the Senate floor, and called its passage "a very sad day" that would compromise the battle effectiveness of the military.
