Sadly, a man of principle cannot win the Presidency. The American people are too stupid and greedy. Ike; We need to go back to being a nation, not an empire.
Corporate interests will not allow Ron Paul to be President. I almost wanna place a huge intrade hedge bet in favor of Ron Paul being voted the GOP nomination for 2012. If for any other reason besides the huge payoff, to boost him a bit in the "talk about" category. He would crush Obama easily and steal tons of progressives into voting Republican, not to mention probably all the moderates.. He can still do it... provided he don't start talking crazy shit to try and peddle for voters. He doesn't need the extremist side of the conservative movement to win, just the principled side. . .
Paul's only chance would be if all the anti-war folks realized Paul was the only anti-war candidate and flocked to the Republican primaries.
