Jeb Bush Trails In Early Iowa Poll

Former Florida Gov. Jeb Bush is trailing six other Republican presidential hopefuls in an early Iowa Republican caucus poll conducted by Quinnipiac University.

Bush takes just 5 percent among the likely Iowa Republican caucusgoers asked about who they would vote for if the caucus were held today -- a 5-point drop from a Quinnipiac poll conducted in February.

Wisconsin Gov. Scott Walker leads the pack with 21 percent of the vote, followed by Sen. Marco Rubio (Fla.) and Sen. Rand Paul (Ky.), who are tied in second place with 13 percent. Sen. Ted Cruz (Texas) takes 12 percent, former Arkansas Gov. Mike Huckabee 11 percent and Ben Carson places just ahead of Bush with 7 percent.

But Bush led on another question: A quarter of respondents said they would definitely not support him for president. Gov. Chris Christie (N.J.) did slightly better; 20 percent said they would not vote for him.

While the latest poll from Quinnipiac reflects a drop for Bush, the HuffPost Iowa Caucus chart, which aggregates all publicly available polls, finds Bush still holding on to second place in Iowa with 12 percent of likely Republican voters in the state supporting him.

Nationally, Bush leads the field of potential Republican nominees with 15 percent, one point ahead of Walker, according to the HuffPost Pollster national chart.

Bush's drop in Iowa follows slight surges for Cruz and Rubio after they officially announced their candidacy. As the race moves forward, poll numbers can be expected to fluctuate for all of the candidates.

The Quinnipiac poll surveyed 667 likely Iowa Republican caucus participants via live interviews on landlines and cell phones from April 25 to May 4.
