Has McConnell Lost Control of His Caucus?

A good point from First Read on the dissension in the Senate GOP caucus:

“Is this what happens when the Senate GOP’s top two leaders — McConnell and John Cornyn — are in an election cycle? Is there tension because some Republicans believe McConnell and Cornyn are so concerned about their own re-elections that they no longer look out for the best interests of the party? It’s never easy being in leadership and being vulnerable to re-election, because it creates this exact concern: confused priorities or the PERCEPTION that their priorities are out of whack.”
