"His departure from Congress, effective next month, comes as the political winds appear to be blowing against the 61-year-old lawmaker and the movement he has spoken for. Some of the movement's most fiery members lost reelection bids last month, including Reps. Allen West of Florida, Joe Walsh of Illinois and Chip Cravaack of Minnesota. Earlier this month, the House GOP leadership unceremoniously removed three conservatives from key committee assignments."
Republican losses in the election weakened his position. The party had hoped to win control of the Senate, but instead lost ground. DeMint played a role in some of the worst defeats. He embraced the candidacy of Todd Akin, even after the Missouri congressman's controversial remark about "legitimate rape" sent the Republican establishment fleeing. And in Indiana, he provided financial support for Richard Mourdock, a conservative who ousted longtime Republican Sen. Richard G. Lugar in the GOP primary but proved too extreme for voters in the general election.
