Rick Santorum has no money. He was a one-hit wonder out of Iowa, rolling along on his strong social conservative credentials.
He was the last of the anti-Romney surge candidates(not counting the quiet and steady rise of Ron Paul). Unlike the other more well-financed candidate, Santorum roused the last-minute enthusiasm of Midwestern farmers, many of which can proclaim their enthusiasm without donating funds to support his campaign.
He has galvanized the social conservative base. Even rabid columnist Michelle Malkin has thrown her supported behind the Pennsylvania Populist.
He has contacts with lobbyists. He supports Big Government, but he does not flip-flop on issues. He does not hold diverse and divergent views which would offend the GOP base. He is strong, sensible, and committed to the well-being of the American people and the country.
