Rich Lowry sees Huckabee as this cycle's Howard Dean:

After many false prophecies, Dean circa 2008 has finally arrived. He is former Arkansas Gov. Mike Huckabee. Not because he will inevitably blow himself up in Iowa. But because, like Dean, his nomination would represent an act of suicide by his party.

Gerard Baker sees Huckabee splintering the Republican party:

Huckabee. It sounds like one of those American restaurant chains popular across the South, the kind of place where on All You Can Eat Tuesdays the patrons down buckets of barbecued ribs and fried chicken while sucking on 32-ounce tumblers of diet soda. Then again, it could be a character from a Mark Twain novel, or a predictably contrived name in the first line of one of those obscene limericks written by bored schoolboys. But President Huckabee, commander-in-chief, leader of the free world?

Update: They just keep rolling in.

Peggy Noonan: But there is a sense in Iowa now that faith has been heightened as a determining factor in how to vote, that such things as executive ability, professional history, temperament, character, political philosophy and professed stands are secondary, tertiary.

Jim Geraghty: Huckabee already had questions about whether he really could appeal to economic conservatives or foreign policy conservatives. It seems, judging by his supporters and his rhetoric, that the one message that has worked like gangbusters for Huckabee since he entered the race, has been his message to evangelical conservatives, “I’m one of you.” Judging by the polls, that community has responded enthusiastically: “Yes, you’re one of us.”That’s a nice bond. But it’s not enough. And for those of us outside that bond, what’s the pitch to get us to mark Huckabee’s name on the box? Good jokes? The irony of seeing Hillary defeated by a guy from Hope, Arkansas? A campaign theme of “I’m one of you” only works for folks who see themselves as “you”, not as “the other guys.”

Stuart Rothenberg: And if electability truly is an important issue for the GOP, Huckabee could be a disaster. While some have argued that he could hold conservatives on abortion and civil unions and appeal to swing voters and even Democrats on immigration, spending and domestic priorities, it is more likely that he would lose conservatives on taxes, spending and immigration and alienate moderates and Democrats on social issues.
