This group is gaining traction. A lot of it. If the GOP picks Romney or Newt(well, they are not going to pick Newt, but for the sake of argument) do you think this is how Ron Paul gets in? http://www.americanselect.org/
It's a possibility. Another would be Gary Johnson moving off the Libertarian ticket in favor of Ron Paul. However, given that Ron Paul just moved past Newt in NH, I'm thinking he's in it to win it for the GOP nod....not a lock, but definitely a good chance.
Romney is the guy for the GOP. Fox news, which is their largest propaganda machine, will attempt to crush anyone who is not Mittens. I think this Americans Elect might be on the something if they can get on in all fifty states. It looks like they are going to make it.
