Columbus -- Gov. John Kasich has picked up a few percentage points in a new poll of registered voters considering candidates in the 2016 presidential field.

But he and 15-plus other candidates trailed billionaire Donald Trump among GOP hopefuls.

Trump also topped the list of candidates that voters said they wouldn't support. The results were included in a Quinnipiac University Polling Institute survey released July 30.

"They love him and they hate him," Tim Malloy, assistant director of the poll, said in a released statement concerning Trump. "Donald Trump triumphs on the stump so far, but do voters really want him? Maybe not so much."

Connecticut-based Quinnipiac regularly gauges the opinions of voters in Ohio and other swing states on candidates and issues. It questioned 1,644 registered voters nationally over the last week on potential 2016 presidential match-ups. The results have a margin of error of about 4 percentage points.

Kasich more than doubled his support among voters in the latest poll, with 5 percent of those questioned siding with his candidacy in the Republican field. That's up from 2 percent in Quinnipiac polls over the past year and a half.

Trump received 20 percent support, up from 5 percent in a May poll. Thirty percent of those polled also said there was "no way" they would support Trump for president.

Wisconsin Gov. Scott Walker and former Florida Gov. Jeb Bush were the only other candidates in double digits, with 13 percent and 10 percent, respectively.

Four other candidates reached 6 percent in the poll. And 12 percent said they hadn't decided yet.

The numbers take on an added significance in the days before the first GOP presidential debate, set for next week in Cleveland. The top 10 candidates in a series of polls will qualify to participate.

Former Secretary of State Hillary Clinton topped Democratic candidates with 55 percent support from those questioned.

Clinton also held a double-digit lead over Trump in potential general election contests but was statistically tied against Bush and Walker.
