To be honest Biden +1 is not enough if he wants to compete statewide
Well, it is a 7 point swing so on a uniform swing it is a 1-point statewide Trump win. However if we assume that this district trends D, then Trump is probably winning by a margin like DeWine's.
I feel like that will happen in the end with Biden matching or exceeding his Texas polling to offset that
Yes, I think a tie in Ohio and Iowa polls probably means Trump is actually up by Reynolds and DeWine margins. The swings in Texas could be crazy, if Biden underestimated by as much as Beto was a 3-4 point Biden win there is possible. That could be a shift of 12-13 points from 2016, and probably even greater in the competitive suburban districts.
