I expected Walker to surge eventually, but not this soon...
I expect a Huckabee comeback in Iowa, but who stands to lose is Jeb Bush, hopefully he doesn't win.
I imagine that a lot of the Ben Carson votes will go to mostly Huckabee, and some to Santorum.
I'm not convinced Carson's numbers are as tenuous as people here seem to think. He isn't getting support based on name recognition by inattentive voters. If anything, that's Huckabee, as evidenced by his being the biggest beneficiary from Romney dropping out. Walker, Cruz or Jindal seem like bigger threats to Carson, but I assume his not holding office is an asset to people voting for him here.
