I still don’t really have much hope that O’Connor will win, and the polling has been consistently on Balderson’s side, but Republicans are worried enough that they just sent Mike Pence to Newark, and now they’ve announced that Trump will be holding a rally in Delaware County this weekend.
I initially thought Delaware County was kind of a weird place for Trump to hold an event (he won it in 2016 but it shifted toward the Democrats) but that’s where Melanie Leneghan (the GOP primary loser) is from. She has not yet (AFAIK) accepted the results of the primary as legitimate, and is suing with a crazy allegation that officials in Muskingum County (where Balderson lives) literally stuffed the ballot boxes in his favor. So this could be an attempt to try to drown out her sore loser act.
As of right now my guess would be something like Balderson by 5, which is big enough the GOP will strut around and claim it’s a massive victory over what all the fake news expected would be a dead heat, while ignoring what an ominous sign it is for November.
