7 Takeaways Post-Iowa Caucuses

7 takeaways from last night's Iowa caucuses.

1. Let's not overplay the results in Iowa. Yes, it was record turnout for the Republicans and a robust turnout by Democrats, but the total is less than 400,000 voters. To add perspective, in the general election just in Iowa ten months from now we can expect 1.6 million people to vote. The caucuses are a signal of some things, but not many things. And every candidate still has to show if they have a broad diverse base of voters - we have only heard from one tiny segment of America.

2. Trump finished second in Iowa, and Hillary squeaked out a bare slim victory, but the frustration and anger in this country at the status quo and the establishment of both parties is real and lasting. If either party thinks this was just a moment in time, and they can go back to the way of doing things they are sadly mistaken. The majority of Americans feel no real attachment to the two incumbent political parties, and desperately want change. The earthquake has already happened, and it is essential that we don't underestimate the foundational damage that has occurred to politics as usual.

4. The road ahead for Cruz, Trump, and Rubio is complicated and problematic for each of them. Each has a path to victory, and each has serious obstacles ahead. Cruz has to show going forward that he can win in higher turnout primaries where evangelicals don't dominate the voter pool. Trump has to show he can get up off the canvas, learn from his mistakes, and win quickly in New Hampshire and then keep it going in South Carolina. Rubio has to figure out a place he will start winning - a series of 2nds and 3rds won't cut it for long.

5. If Trump really wants to win the nomination, the Iowa results show that he needs some campaign pros who understand messaging, targeting, and can provide discipline. To that end, Trump needs to quit relying on public polls for direction, and hire some folks who know what they are doing. He probably needs to win New Hampshire before any seasoned veterans will go to work for him. He also needs to demonstrate some humility and that he's able to seek advice from others. For starters, he did show some humility in the aftermath of the Iowa loss, but we will find out if that was a real change or just an instance.

6. Organization matters to a point, but don't overplay it. Passion and momentum are still two of the most important ingredients in politics. Hillary had the best organization of anyone running, had all the paid staff one could hire, and she ended up in a tie with a candidate built on volunteers. Yes, Ted Cruz won Iowa, and his organization was the best, so props to him. But, keep in mind, two candidates (Trump and Rubio) finished right behind him who spent hardly any time in the state, and who had limited organizations. And Trump and Rubio beat the total vote performance of all previous GOP caucus winners.

It is going to be a fascinating ride in the months ahead. The voters as of last night now have their hands on the steering wheel and there is no telling where they might direct things in this race for the White House.

There you have it.
