I lurk around lefty sites as well and you are correct. I have seen many a post telling John Kerry to hang it up and he is delusional if he thinks all those who voted for him actually voted for him. They are openly admitting now, for the purpose of disuading Kerry and his supporters that they voted against George Bush and with Bush off the ticket in 2008, Kerry loses a significant amount of his "voters".
Just saw a couple of posts with Hillary on it for president. They seem like they have decided that Hillary will probably run in 2008. Looks like she might just turn out to be the favorite for the Leftists if she plays her cards right.
