He went on to defend Manchin's position on the amendment -- a position which 80 other senators, including Graham, also took. "I can tell you this, Joe," said Graham on the call. "You can't get 80 senators in this environment to agree that Sunday should be a day off."
But among the small group who voted for
Paul's amendment were tea party stars Sen. Pat Toomey
, R-Pa., Mike Lee
, R-Utah, and Jim DeMint
The Club for Growth has already identified
Graham as a potential 2014 target.
Meanwhile, Manchin makes an odd target for Paul: He is one of the most conservative Democrats in the Senate, but more importantly, he is popular and appears to be in excellent shape to win his reelection campaign. Rand PAC spokesperson Jesse Benton
said they have data that shows the West Virginia race tightening and think the ad "could be a game changer."
