The Washington Post:
Jim DeMint can rest easy. It is unlikely that folks like Mike Lee, Ron Johnson or Sharron Angle will be co-opted if they win. But come November there may be some new Republican senators eager to join the club. While the media has focused on the rise of the Tea Party movement and the success of conservative insurgents in GOP primaries, there is another smaller insurgency taking place under the radar screen -- a quiet insurgency of more moderate Republicans for whom fiscal discipline is not a top priority.
I repeat: we need to win on the issues.
