Trump won the district by 30 points. Grab Popcorn for a Trump meltdown if O'Connor wins.
Almost 9.000.000 voting age people in Ohio. https://www.census.gov/library/visualizations/2016/comm/voting_age_population/cb16-tps44_voting_ohio-social.html Edit: I'm dumb
Oh! This was a Congressional district. So not a statewide race. Sorry. The coffee is slow to work this morning. https://www.census.gov/mycd/?st=39&cd=12 582.000 people over the age of 18. Still not great, but better. I can't find any stats right now on how many of those are actually registered to vote. TBH, I'm not too convinced that's a useful stat in this context anyways. More of a sanitizing one. "Participation rates go up once you only factor in people who at least minimally engaged with the system!"
