Former President Donald Trump participated in a radio interview with Ohio 98.9 on Tuesday to boost his favored Senate candidate J.D. Vance in the state during the final hours of the race.

While on the show, Trump was asked about the leaked Supreme Court draft opinion overturning Roe v. Wade and denounced the leak as "demeaning" but did not comment on the draft itself. Notably, Trump vowed to appoint justices who would overturn the nearly 50-year precedent.

Trump went on to get out the vote for Vance but acknowledged, as he always does, that his preferred candidate wasn't always on his side.

"Well, I've liked him. He was rough on me but so was everybody else, they all were, really. But he was pretty, I would say normal rough, relatively speaking," Trump said. "And I just thought he was very exceptional. He came back a long way as you know, he retracted everything. Overall, I just think he's gonna be very good."

"They're all good," Trump added. "But J.D. is going to win."

Polls closed at 7:30 p.m. across Ohio, where voters cast ballots in primaries for the House of Representatives and Senate, as well as for governor, attorney general, secretary of state and auditor.

Key races in the state are expected to shed light on the endorsement power of both President Joe Biden and former President Donald Trump.

The Ohio secretary of state's office released final early voting totals -- showing that 301,837 absentee ballots were requested by-mail or in person, and that 263,542 votes had already been cast statewide.

Those numbers surpass the 2018 total of 300,765 absentee ballots requested through the end of the early voting period and 260,443 total early votes cast.

In the final hours of Ohio's Senate primary, Republican candidates were quick to praise the prospect of overturning Roe v. Wade as the stunning leak of a Supreme Court draft opinion rocked the race overnight.

"I do think Roe was a big mistake. And I think if the Supreme Court overturns it, it will be a big success for the pro-life movement," J.D. Vance, who got former President Donald Trump's endorsement, told ABC News Congressional Correspondent Rachel Scott.

"If it gets overturned, we're gonna have a fight here in the state of Ohio. And I think I'm going to be on the front lines of that fight trying to get us here in Ohio to protect it," he added.

Rep. Tim Ryan -- the Democrats' likely candidate in the hotly contested race, who once opposed abortion rights but changed positions in 2015 -- called it a "freedom issue" that he predicted would motivate a lot of women "to vote for a senator who would be on their side."

"I think in many ways to abortion is, in some sense, an economic issue as well. Should a woman be able to plan the size of her family? Should a woman be able to plan when she has a pregnancy? This is a freedom issue, really, for me, and I think it's a freedom issue for a lot of these women," Ryan told ABC News Senior Washington Reporter Devin Dwyer.

Ohio and Indiana are among the 26 states which are likely or certain to ban abortion if Roe falls or is gutted, according to the Guttmacher Institute, an abortion rights research organization.
