How can Ron Paul win?

I have talked to people in and out of the campaign and it seems they all are saying the same thing. He MUST win Iowa, but there is a problem, Bachman. She has huge support and Ron Paul seems to be coming in rather low in that state. But if he wins the Iowa straw poll, he will receive the publicity and chatter needed to disrupt Bachman's efforts. So as Ron Paul supporters the best thing we can do is continue to support him and make phone calls at www.rp2012.org
