Huck will suck all the wind out of the Santorum energy; he's right about that. I think 2-1 is way too high for Huck here, but I think 20-1 is too good for Santorum too.
I don’t necessarily see any advantage for Huck over Santorum, but then again, this is not my niche of the electorate. There appears to be about 30% of the Iowa Caucus voters who are simply going to vote for someone who emphasizes nothing but social issues. RS got them all in 12, Huck got most of them in 08.
