For every conservative who is so angry at McCain that they would rather have Hillary as president there are 5 independents and a democrat or two who would vote for him instead of Hillary. Remember the Democrats who voted for Reagan by the millions?
McCain can get all the votes he needs from the center, not the hard right, so that we don't have to deal with socialized medicine, cancellation of Bush tax cuts, cut and run from WOT, universal pre-k, and the most repulsive aspect of a hillary presidency...

Obviously, you have not been around here long.
