I don't even see why the AR Dems feel the need to go through the trouble. Who cares if a few delegates vote Wolfe's way? Obama already has the nomination locked up by a substantial margin in the delegate count.
They want the symbolism of a unanimous vote by the delegates in Charlotte. It always looks bad when the incumbent President doesn't get that.
I guess that makes sense, but I just don't see how that would really impact much come the election. If anything, all of this delegate nonsense from both parties is just going to polarize them even further.
