Zogby Analytics just completed a massive poll of voters nationwide. Among the sample of 884 GOP likely primary/caucus voters, former Governor Jeb Bush leads with just 13% of the vote, followed by neurologist Dr. Ben Carson and Kentucky Senator Rand Paul tied with 11% each, Wisconsin Governor Scott Walker 9%, Florida Senator Marco Rubio and former Arkansas Governor Mike Huckabee tied with 7%, Texas Senator Ted Cruz and Developer/Reality Star Donald Trump tied with 6%, and New Jersey Governor Chris Christie 5%.

Other candidates tested included former Texas Governor Rick Perry with 4%, former Pennsylvania Senator Rick Santorum 3%, Ohio Governor John Kasich 2%, and three candidates tied with 1% each - Louisiana Governor Bobby Jindal, former Hewlett Packard CEO Carly Fiorina, and South Carolina Senator Lindsey Graham. Former New York Governor George Pataki came in with .4% support.

The online poll was conducted June 5-10.

Mr. Bush performed much better among self-described Republicans (18%) and independents (2%). He also received double digit support among all age groups - 18% among 18-29 year olds, 13% with 30-49 year olds, 10% among 50-64 year olds, and 14% among voters over 65.

Dr. Carson also did better among Republicans (11%) than independents (5%) and did best with 50-64 year olds (15%). He polled 12% with voters over 65, 11% with those 30-49, but only scored 4% among the youngest group.

Dr. Paul's best support was among independents with 24% -- to only 7% among GOP voters - and among voters under 30 (23%). He received 12% among 30-49 year olds but drops to 6% among 30-49 year olds and 5% among those over 65.

No other candidate received double digit support among any sub-group.

The pros and cons that face each candidate have been discussed already and they have not really changed. But as we enter the summer of 2015, no clear frontrunner has emerged on the GOP side and is not likely to until at least the fall when presumably a few candidates will withdraw for lack of funds, lack of support, or a gaffe in the debates or on video. But this is how it looks with a very large sample of likely voters. The top tier of candidates have carved out their own niches thus far - but no one is even close to the prize just yet.
