Ron Paul will do well. There are guys running who will do worse.
Ron Paul, last time, did better than a lot of guys who ran last year. Did better than Hunter, Thompson, Tancredo, Giuliani, Thompson, Brownback, Gilmore. Didn’t do as well as McCain, Romney, Huckabee. And these results came when he started as an unknown. This time around, he’s in 4th place, like he was last time, with Palin, Romney, Gingrich ahead. That’s the current poll numbers, roughly.
Cain will likely be moving up in the polls based on the reaction to his debate performance. They say Gingrich hurt himself, so you could see him falling in the polls. Bachmann is moving up a bit too.
Ron Paul has no chance whatsoever. He will pull no more than 2-4% of the vote and that’s it.
