In this Jan. 4, 2013, photo, House Speaker John Boehner of Ohio, walks to a strategy session with GOP members, on Capitol Hill in Washington at the start of the first full day of business for the new 113th Congress. Republicans in Congress who took the politically risky step of voting this week to raise taxes now find themselves trying to fend off potential primary challenges next year from angry conservatives. These lawmakers wasted little time in attempting to deliver an explanation that would be acceptable to the tea party and the GOP's right flank, and, perhaps, insulate themselves from a re-election battle against a fellow Republican. They've started defending the vote as one that preserves tax cuts for most Americans, while promising to fight for spending cuts in upcoming legislative debates over raising the nation's borrowing limit.
