As far as the Republican party is concerned, Ron Paul is the only one who should even be allowed on the poll, as he is the only one who actually represents Republican ideals... not the neo-con crap that has been rammed down our throats for the past couple of decades.
Unfortunately, as Breukelen so astutely put it, Paul doesn't stand a snowball's chance in hell... so now I have to make my mind up with the Democrats, which have been fairly disappointing leading up to this election considering how much strength they should have with rallying a country together that has been disheartened by a small group of giant, greedy assholes.
