History suggests that the party not represented in the White House does well in midterm Congressional elections 鈥� and this year, Ohio鈥檚 statewide races are likely to draw a lot of national attention.

Currently, Republicans control Congress and the White House, and President Trump鈥檚 popularity is at a historic low.

In Ohio, there are no incumbents running for governor, attorney general, auditor, secretary of state or treasurer. Not to mention, the entire Ohio House is on the ballot.

Kyle Kondik, an Ohio native and the editor of the political newsletter , says this is a huge test for Democrats in Ohio.

鈥淚f Democrats can鈥檛 perform well in Ohio in this kind of environment, I think it does lead one to question whether the state鈥檚 kind of perpetual swing state status might be sort of going away,鈥� Kondik says.

The newsletter forecasts Ohio as leaning Republican in the governor鈥檚 race, and leaning Democratic in the U.S. Senate race.

In the Ohio governor race, Ohio Attorney General Mike DeWine and Lt. Gov. Mary Taylor are competing for the Republican nomination, while the Democratic side is down to a five-way race between former CFPB director Richard Cordray, former U.S. Rep. Dennis Kucinich, state Sen. Joe Schiavoni, state Rep. Connie Pillich, and Ohio Supreme Court Justice Bill O鈥橬eill.

According to the newsletter, DeWine is the 鈥渂ig primary favorite鈥� among Republicans, while Cordray seems the likely nominee but 鈥渋s far from dominating and has not really scared off his rivals.鈥�

So far, just U.S. Rep. Jim Renacci and Cleveland businessman Mike Gibbons have stepped up to challenge incumbent Sen. Sherrod Brown.
