I was chatting in e-mails with Dr. Peterson, the author of the
Stop the North American Union site, 1 day and she seemed to think that Dr. Paul might run as the Constitution Party candidate if he doesn't get the nomination. Last night he was asked by Allan Colmes (i think?) if he would consider running as an "independent" and he said "no", but he was never asked about a "3rd party".
There is still a lot of time left, but things are happening a lot earlier this election cycle than ever before. That means that if he doesn't get the nomination that there is still a lot of time to get people to dump the neo-conned republican party and register for the Constitution party. A good grass roots effort could successfully get him on the ballot in every state, and I think Ron Paul has already shown his ability to compete on a national level, considering multiple poll standings showing him winning or coming in 2nd in the 1st 2 debates.
