Trump, Hillary head into Iowa caucus as frontrunners

DES MOINES, IA (KTRK) -- Iowa voters will go to caucus tonight, weather permitting, setting the 2016 election cycle into motion.

The frontrunner, Donald Trump seems poised to win here. The latest polling has him in first place, beyond the margin of error, ahead of Texas Senator Ted Cruz.

Polling also suggests half of Trump's support is from new voters. Will they actually show up? Will the projected snowfall today deter some of them from taking the time to caucus? Trump thinks they'll follow through and help him win.

PRESIDENTIAL ELECTIONS: How primaries and caucuses work

"By far, the Trump voter, the Trump person, is the most loyal by far," Trump says.

"You are going to make a decision soon. Monday. And I'm telling you we're going to do a hell of a job. We are going to make America great again. I promise."

We've talked to a lot of Trump supporters in several states over the past few months. And without exception, the thing all of the say they like about him is his politically incorrect, plain spoken approach to politics.

It is shaping up to be the year of the establishment versus the outsider on both sides of the aisle. Today should be a fascinating.

On the left is Hllary Clinton. The former first lady, senator, and secretary of state was working hard the entirety of the weekend to persuade the undecideds and motivate her supporters to turn out.

She's facing a stiffer than expected challenge from Senator Bernie Sanders of Vermont. He is drawing large crowds across the state and could be poised for an upset.

All the speculating and punditry ahead of the vote is about to end. Caucusing begins tonight at 7pm.
