Santorum is at 10% in Iowa and rising, per both Rasmussen and PPP, while Newt is at 14%/17% and falling.
Santorum is not perfect, but he's more conservative and more electable than Newt.
When polls have fluctuated wildly throughout the campaign, why do you insist on supporting Newt and attacking supporters of all the conservative candidates as stooges for Romney -- because of a 4%-7% lead over a far better candidate?
Look, I love the guy, but I can't see how you can seriously make that claim. Santorum's appeal is limited to hard-core conservatives. Rougly 10% of the electorate. He is about as electable as Howard Dean.
And should he win Iowa, what then? Dean won there too. Santorum has put ALL of his effort there. He has done a townhall in every county. Romney is going to win NH regardless. Gingrich is safe in SC, and looks strong in FL.
Winning Iowa will delay the inevitable for a few weeks for Santorum. The best he can do is this election's Huckabee.
