COLUMBUS - Presumptive GOP nominee Donald Trump and Democrat Hillary Clinton are in a dead heat for Ohio's votes in the all-important swing state, according to a Quinnipiac University poll released Tuesday.

Both would receive about 40 percent of the vote, according to the most recent poll, which comes one month after polling showed Trump had a slight edge over Clinton in the Buckeye State.

Poll: Trump edges Clinton in Ohio in battle of unpopular candidates

In the past month, Trump has suffered some self-inflicted wounds, including attacking a federal judge of Mexican descent and doubling down on a ban on Muslims following the shootings at an Orlando gay club. Clinton has slightly more support from Ohio Democrats – 80 percent would vote for her – than Trump has among the state's Republican voters, 76 percent of whom would vote for Trump. Quinnipiac also polled in Florida and Pennsylvania.

"The at-times bitter verbal battles between Trump and some Republicans leaders is showing in these numbers," said Peter Brown, assistant director of the Quinnipiac Poll, in a statement. "In these three key states, Clinton is doing better, and in the case of Florida much better, among Democrats than Trump is among Republicans. Traditionally GOP presidential candidates score better on this party loyalty test."

About 59 percent of Ohioans said Trump's comments about the federal judge overseeing his Trump University case were racist, but 33 percent disagreed.

Both nominees remain unpopular with Ohioans. They were tied with 59 percent of voters polled saying they had an unfavorable view of either candidate. In comparison, 40 percent of Ohioans had an unfavorable view of Democrat Bernie Sanders, who would lead Trump 48 percent to 38 percent head-to-head in Ohio, according to the poll.

Ohioans thought Clinton was better prepared to be president, had higher moral standards and was more intelligent than her GOP rival.

But they thought Trump was more honest, more inspiring and a stronger leader. Trump would be the better guest for a backyard barbecue, but Clinton would be more helpful in a personal crisis.
