As Gingrich exits, the Paul campaign continues. His supporters took more than half of the delegate slots in Massachusetts over the weekend:

[T]he losses are an alarming indication that Romney's campaign organization is still woefully underdeveloped, even in the state where he served as governor, and where his campaign headquarters are located. … Massachusetts wasn't the only state where Paul notched delegate victories this weekend.

The campaign announced Sunday that Paul supporters will make up 74 percent of the delegates at the Louisiana GOP convention, putting Paul in prime position to pick up a sizable chunk of the state's national convention delegates. Paul supporters also reportedly made inroads at Alaska's GOP convention, overcoming staunch opposition from the state party Establishment. Even Paul's campaign advisors admit that, despite the success of their convention strategy, it would be virtually impossible to deny Romney the 1,144-delegate majority he needs to win the nomination on the first ballot. But delegates also vote on the convention chair, the vice president, and the party platform, and Romney could have a hard time controlling those votes if the delegate team he brings to the convention is loyal to another coach.
