Obama says he’ll withdraw his support of wavering Democrats on Health Care, and not campaign for them. It would seem to me that this isn’t exactly a threat. In fact, if I were one of those wavering Blue Dogs, I think my inclination would be to ask the White House if they would put it in writing. Perhaps Obama could twist more arms byÂ threateningÂ to show up at key campaign events. You can’t say “no” to the President, after all.
