I heard that he was persuaded by emails etc.. that reminded him he wouldn't be Gov. without the support of conservatives--and they(we) had to overlook a LOT!
Coincidentally, I emailed him about 4 days before his endorsement and said exactly that. Thank me! (hahaha) Not that it did any good.
Did your e-mail have a naked picture of Eleanor Roosevelt attachment? just curious.....:o) fsf
