GOP presidential hopefuls head to Iowa Freedom Summit

Fox News 

WASHINGTON –  Call it the unofficial kick-off of the 2016 Republican presidential race. 

Two-dozen Republican politicians -- nearly half of them at least considering a run for the White House -- are descending on downtown Des Moines this weekend for the Iowa Freedom Summit, where they'll test their conservative chops before a sold-out crowd. 

The summit, which was held in New Hampshire last time around, is only in its second year but is drawing an impressive amount of GOP star power. The heavy-hitting lineup, in the first-in-the-nation caucus state, effectively makes it the first major candidate forum of the cycle. 

"Odds are, the next president of the United States will be there," said Rep. Steve King, R-Iowa, who is sponsoring the event along with Citizens United. 

The Saturday event is being held as the field of potential 2016 candidates grows ever-larger, with 2012 nominee Mitt Romney and former Florida Gov. Jeb Bush making moves toward a run. 

The two former governors will not be in Iowa, but here's who will: New Jersey Gov. Chris Christie, former Texas Gov. Rick Perry, Texas Sen. Ted Cruz, former Arkansas Gov. Mike Huckabee, and former Pennsylvania Sen. Rick Santorum. 

Others slated to speak include neurosurgeon and conservative firebrand Ben Carson, Wisconsin Gov. Scott Walker, former vice presidential candidate Sarah Palin and businessman Donald Trump, as well as former Hewlett-Packard head Carly Fiorina and former U.N. ambassador John Bolton. 

All at least carry with them presidential speculation; most are openly flirting with a bid. 

The Iowa summit, which lasts all day Saturday, will be their biggest chance so far to test-run their messages with Iowa voters.
