Poll: No Clear Front-Runners, Most Voters Undecided In 2016 GOP Race

WEST LONG BRANCH, N.J. (CBSNewYork) -- The field of Republican candidates entering the 2016 race for the White House keeps growing, with former Florida Gov. Jeb Bush formally announcing his candidacy Monday.

However, no one candidate is tops among voters.

The latest Monmouth University Poll found that undecided is the most popular response when Republican voters nationwide are asked who they support as their party's leader.

In fact, voters are finding it difficult to even to identify a clear "top tier" in the field of 16 possible 2016 Republican presidential candidates, according to the poll.

"You would be hard pressed to look at these results and identify an emerging top tier in the Republican field, let alone a so-called front runner," said Patrick Murray, director of the Monmouth University Polling Institute in West Long Branch, NJ.

When asked to name who they would like to see as the party's nominee for president, Republican and Republican-leaning voters are divided among:

Commentator Dr. Ben Carson (11%).

Wisconsin Gov. Scott Walker (10%).

Former Florida Gov. Jeb Bush (9%).

Florida Sen. Marco Rubio (9%).

Former Arkansas Gov. Mike Huckabee (8%).

Here's how other candidates and potential candidates rank:

Kentucky Sen. Rand Paul (6%).

Texas Sen. Ted Cruz (5%).

New Jersey Gov. Chris Christie (4%).

Former Texas Gov. Rick Perry (4%).

Former Pennsylvania Senator Rick Santorum (3%).

Businesswoman Carly Fiorina (2%).

South Carolina Sen. Lindsey Graham (2%).

Businessman Donald Trump (2%).

Louisiana Gov. Bobby Jindal (1%).

Ohio Gov. John Kasich (1%).

Former New York Gov. George Pataki (0%).

As far as issues most important to Republican voters, national security and gun control were at the top, according to the poll.

The poll was conducted by telephone from June 11 to 14, 2015 with 1,002 adults in the United States.
