Many Ohio voters still like former Vice President Joe Biden.

Of all the top Democratic presidential candidates, only Biden beat President Donald Trump head-to-head in Ohio in a poll released by Quinnipiac University on Thursday morning.

In a race between Biden and Trump, 50% of the 1,431 likely Ohio voters surveyed said they'd vote for Biden. Trump would get 42%.

Trump is in a dead heat with the five other leading Democratic contenders, U.S. Sens. Cory Booker, Kamala Harris, Bernie Sanders, Elizabeth Warren and South Bend, Indiana mayor Pete Buttigieg.

The results released a week ahead of Trump's Aug. 1 rally in Cincinnati show Trump's popularity may have slipped in Ohio, a state he won by eight percentage points in 2016.

That means Ohio may regain its swing-state status in 2020.

Women, independent and black voters in Ohio went heavily for Biden, according to the poll. Biden won among Ohio women 53%-40%.

“Vice President Biden’s blue-collar roots aren’t necessarily the key to his success," said Peter Brown, director of the Quinnipiac poll. "It’s his half-century in Democratic politics and almost universal name recognition."

Biden also led the pack among Ohio's Democrats, with 31% backing him. Sanders and Harris were tied for second with 14% each. Warren had 13% of Democratic support and Buttigieg got 6%.

The poll had a margin of error of plus or minus 3.2 percentage points.
