Ohio Treasurer Josh Mandel announced he will be running to unseat Democratic senator Sherrod Brown in 2018, a potential rematch of their 2012 contest which Brown won by 5 points. Mandel has been using Trump rhetoric in public campaign events as well as his campaign announcement video. Also interested in a possible run is Rep. Pat Tiberi (R-Ohio), a more moderate Republican more aligned with Governor John Kasich who refused to endorse Donald Trump during the presidential election.
Brown was first elected to the U.S. Senate in 2006 and re-elected in 2012 – both very favorable cycles for Democrats. Donald Trump won Ohio by 8 points in the last election. Historically, the party that controls the White House tends to lose seats during midterm elections, though the Senate Republicans have a very favorable calendar for 2018. The question is what will the national and local dynamics be after two years of Trump as president. If times are good and he retains the popularity that got him elected, then odds are Sherrod Brown will be in for a tough race. If the economy is bad or Trump is mired by unpopularity, having such a close association with him could be a negative for a candidate like Mandel.
