Why are some people acting like Obama understands economics or the Free Market System?

Obama is going to change America (he will win for sure, look at the polls). Maybe it will be good, maybe it will be bad. McCain is going to keep things the same...it's not working. He voted with Bush over 90% of the time. He voted with an idiot over 90% of the time. You talk about Obama's connections with radicals...isn't president Bush pretty radical? Attack countries for no real reason? I think this whole Obama is radical is just false and the only one's falling for this is the people that believe McCain is a good candidate. I am pretty sure getting McCain supporters to vote for McCain is kind of pointless. It's basically over. Time to start thinking forward republicans, to next election.
