Doubt my wisdom is much different than the conventional wisdom, but here goes:
Go home, folks. Mike Huckabee has suspended his campaign, and good riddance. He can go back to selling patent medicines or whatever it is he does in between campaigns. Rick Santorum isn't going to be president in any world we know. Jim Gilmore barely made it onto the stage. The only candidate in the bottom tier that I really liked is Carly Fiorina, but in the end she wasn't able to turn early momentum into something sustainable. I suspect we'll be hearing from her again, but as a surrogate for one of the other candidates.
Big Christie vs. Karate Kasich. These two candidates got bupkis in Iowa, but both have a chance to keep their campaigns going in New Hampshire. Only one will survive. Of the two, I'd pick Christie, but in the long run he's really running for Attorney General. Kasich has gotten endorsements from approximately 4,387 publications in New Hampshire, but it's difficult to see a path forward for him unless he wins New Hampshire outright, which isn't likely to happen.
It's my turn! Jeb Bush has enough money to keep going all the way to the convention, but he really ought to go home. He's not going to overtake his protege turned nemesis Marco Rubio. Deep down, I suspect he knows this, but I don't think he'll go away quietly or graciously. Too bad, really.
Voices heard, but not heeded. Rand Paul did get a delegate, but that's about all he got. He's not going to make it and probably should start tending to his campaign to return to the Senate. Depending on what happens in the next four years, he may have another opening later on. Ben Carson is a wonderful man, but he's not going to make it.
Rubio rising. Marco Rubio is certainly a viable candidate after finishing strongly last night. His speech sounded like a victory speech. It's a bit presumptuous, but he's certainly moved past Bush, Christie and Kasich in the "establishment lane." He's the most talented politician in the field, but he's got a lot of work to do to convince people he's not a squish. If he holds off Kasich and Christie in New Hampshire, he's got a chance to go a long way.
Classy and huge. The invincible Trump wasn't invincible after all, at least in Iowa. He threw the kitchen sink at Ted Cruz, but in the end was not able to turn his rock star crowds into enough caucus attendees to win. If I were Trump, I'd be very nervous about Rubio at this point. It will be interesting to see if he turns his invective machine in Rubio's direction, and away from Cruz, at least for the next week or so.
Cruzin'. Ted Cruz wins Iowa, turning his superior organization and some key endorsements into a narrow victory. The most significant thing about his win is that he campaigned against ethanol subsidies and still won anyway. If he can make a decent showing in New Hampshire, he'll stick around and have a chance to do well in the South. Certainly a contender.
Bern and Hill. Now that Martin O'Malley has dropped out, it's between an ancient socialist and Lady Blackberry Albatross for the Happy Days Are Here Again side of the aisle. Mrs. Clinton has the hellhounds on her trail at this point and if she gets crushed in New Hampshire, as seems likely, it will be interesting to see how things shake out. Bernie Sanders is not going to be president under any circumstances, but if he wounds Clinton sufficiently over the next few weeks, you can expect to see a lot more of Joe Biden.
