To be blunt, Mitt Romney with some $250MM in personal assets and lots of friends in New England thinks he is the only candidate with cash.
There are many of us with deeper pockets than New England Liberals who despise Romney as much as the Romney clan despises Gingrich. They despise Gingrich so much that I think the U.S. Secret Service had better keep tabs on Mr. Gingrich and keep him safe. I pray they do. There are moderate nut balls out there, particularly in California. (They sing the gay marriage song.)
