I grew weary of the argument among various talking heads that Huckabee was taking votes away from Romney; i.e., if Huckabee weren't in the race those votes would most certainly go for Romney.

That is not the case with me. I would vote for Huckabee, I would vote for Ron Paul (I think), I might even vote for McCain (and come November might have to). But I wouldn't vote for Romney.
