What in the world are we to make of the latest version of Mitt Romney?

He's now so peace-loving, so reasonable, so very different from the bellicose and belligerent Romney of the very recent past.  

He's still surrounded by a bunch of neo-con ex-Bushies advising him on foreign affairs, however.  

Are there any limits to what he'll say to get elected?  Does he actually believe anything?  Is there any there there?
