It's caucus day in Iowa. Donald Trump is hoping his supporters will come out and caucus him to victory.
FOX's Jared Halpern reports from Des Moines:
The polls here suggest tonight is Donald Trump's to win....
(Trump) "I thought real estate people in New York were bad. These politicians are the worst liars, wow."
But the big question, can Trump's enthusiam translate to votes or can caucus-goers still be swayed in the final hours?
(Cruz) "Stand and speak for us. If we stand together we will win."
Texas Senator Ted Cruz considered Trump's closest competitor.
Most Republicans are doing last minute appeals here in Iowa, though Governors Jeb Bush, Chris Christie and John Kasich all spend caucus night in New Hampshire.

For the leading Democratic presidential hopefuls... it's a tight race.
