I just saw his half-hearted endorsement on FOX. The basis for his endorsement was money and organization. Oh and beating Obama (due to money and organization). No policies or anything specific. Don’t really know whaat to make of it.
RE "Don't really know what to make of this" -- How about, the GOP has tentacles, embeds, promises of power that we have yet to uncover or imagine. And people are weak and easily bought off... even those in the Tea Party... I'm thinking DeMint in particular..
