Ron Paul is so damn messy, it's almost endearing. However, he is the only Republican candidate (as far as I know) that is ambivalent to same-sex unions even if it's only at state levels so that deserves some cred.
Right. Santorum won 50% of the Democrat vote (it was an open primary). Were they trolling or could Santorum give Obama a run for his money if he's chosen as the nominee.
There's a good chance that at least a significant number of them were trolling. It isn't unheard of for the opposing party to vote for their opponent's weakest candidate so their own nominee has a better chance of going up against the weak nominee and winning.
