That same poll shows Ohio's Republican attorney general, Mike DeWine, with a much more narrow 41.8-37 percent lead over Democrat Richard Cordray, the former director of the Consumer Financial Protection Bureau (CFPB), in the race to succeed Gov. John Kasich (R).

The survey shows Brown with 49.2 percent support among likely Ohio voters, while Renacci garners 31.8 percent support.
Another 19.1 percent remain undecided, giving Renacci some room to close the gap.
"In both races, the outcomes will hinge on how late-deciding voters break on election day," Tom Sutton, the director of the Community Research Institute at Baldwin Wallace University, said.
Polls have consistently shown DeWine and Cordray, who left his post at the CFPB last year just before announcing his gubernatorial bid, locked in a tight race.
The Baldwin Wallace University survey also showed that a little more than 21 percent of respondents remain undecided on how they would vote in the gubernatorial race.

The Cook Political Report, an election handicapper, currently rates the Ohio Senate race as "lean Democrat" and the governor's race as a toss-up.
The Baldwin Wallace University poll surveyed 1,048 likely Ohio voters from Sept. 5-15. It has a margin of error of 3.6 percentage points.
