COLUMBUS - With just one week until Election Day, Ohio's governor candidates remain locked in a tight race while Democratic Sen. Sherrod Brown appears poised to win his re-election bid easily.

Despite months of campaigning and millions of dollars, Democrat Rich Cordray and Republican Mike DeWine have done little to move the needle on the super-close race. The two major-party candidates remain in a virtual tie, according to a Baldwin Wallace University Community Research Institute poll released Tuesday.

Here are a few takeaways from the poll:

1. Ohio governor: Too close to call

Expect the Ohio governor's race to go down to the wire next week.

The Baldwin Wallace poll had DeWine at 39.4 percent, Cordray at 38.8 percent, Libertarian Party candidate Travis Irvine at 4.1 percent and Green Party candidate Constance Gadell-Newton at 1.9 percent. Undecided voters comprised 15.8 percent.

Cordray gained a bit of ground, 1.7 percentage points, since the last poll conducted in September.

2. More Ohioans know DeWine

DeWine, the current state attorney general, entered the race with the best name recognition of any candidate, and he'll end it that way. Republicans like him. Democrats don't. And just 20.7 percent of voters had never heard of him.

More voters had an unfavorable view of DeWine (42.3 percent) than favorable (37 percent.)

Compare that with Cordray, whose last job was heading the Consumer Financial Protection Bureau, a consumer watchdog agency in Washington, D.C. Among likely voters, 37.2 percent said they didn't know enough about Cordray to have an opinion. Of those who had heard of the Democratic gubernatorial candidate, 31.6 percent had a favorable view of him and 31.2 percent had an unfavorable view.

3. Sherrod Brown by a landslide

After three debates and a slew of negative ads, Democratic Sen. Sherrod Brown remains the overwhelming favorite to win re-election against Republican U.S. Rep. Jim Renacci.

Brown led Renacci in the Baldwin Wallace poll, 51.2 percent to 31.7 percent.

Renacci is trying to ride Trump's coattails in Ohio, but even 18 percent of Republicans had an unfavorable view of Renacci.

4. It's health care (and also the economy), stupid

Health care and the economy are the top issues on voters' minds in both the Ohio Senate and governor races.

In the governor's race, 96.5 percent of likely voters said the economy was somewhat or very important and 95.9 percent of likely voters found health care somewhat or very important.

Republicans are hoping voters will focus on the economy because low employment and U.S. economic growth have many Ohioans feeling good about it. Democrats prefer that voters think about the health care they might lose under GOP control.

Speaking of health care, there's a reason why Democrats have hammered Republicans on protecting pre-existing conditions: 73.1 percent of likely voters said it's very important to keep that portion of Obamacare. That includes 86.4 percent of Democrats and 60.3 percent of Republicans.

DeWine has said he supports coverage of pre-existing conditions, but he also joined a lawsuit opposing Obamacare.

Other top issues included taxes, gun policy and immigration.

5. Mr. Unpopular: Sen. Portman

Two years after a landslide election, Republican Sen. Rob Portman's approval rating was lower than Trump's.

Just 33.4 percent of likely voters approved of the job the Terrace Park Republican was doing. Even Trump had a higher approval rating: 44.2 percent.

About 29.8 percent of voters disapproved of Portman's job performance and another 36.7 percent weren't sure.

The Baldwin Wallace poll was conducted between Oct. 19 and Oct. 27 and has a margin or error of plus or minus 3.8 percentage points.
