I don't think Ron Paul will be the Americans Elect nominee. I contend that it'll be Buddy Roemer.
I dont think either Paul or Roemer will be the nominee. Roemers campaign is Bob Smith 2000 all over again. Huntsman, Sanders, Bloomberg, and Johnson all have stronger support. If Johnson declares for the nomination (and he might) he could win it handily, take on Roemer as his AE running mate, and someone else as his Libertarian running mate. Oddly enough, if he does, by a miracle, win, then he is going to have the choice of one of his two running mates becoming VP, which could lead to a Constitutional crisis.
Keep in mind, Rocky Anderson is also seeking the nomination, and is in talks with the Green Party for their nomination as well.
