Money does not rule Politics and the roaring Huckabee Machine

Many political comentators have been talking about how money is the best asset you can have on a political campaign. Not True. Look at Mike Huckabee who just hit 17% in the USA Today/Gallup poll. With less money than Mitt Romney, Rudy Gulliani and even Ron Paul, Huckabee is leading in Iowa and 2nd in the national poll. So the question is how did Huckabee do this? Most insiders wrote Huckabee off in the early election, but he somehow legitmized himself, leading to votes.
(Note: Huckabee has come under fire lately)
