I think the jist of this article is wishful thinking by rooters. Paul has virtually no common ground with Romney.
Oh? Grab "Liberty Defined". Paul has no problem with states 'experimenting' with individual mandate health care. He has no problem with States making abortion legal. He has no problem with States or local governments restricting 2nd Amendment rights. He takes the 'powers' statement in the 10th Amendment and reads that as States have the complete right to restrict fundamental individual rights (which is a slap in the face of original intent). You can find almost every RINO issue of Romney's and find Paul agrees with it, just on a State versus Federal level.
