The only four I am fairly certain he will win (at this point, before any new scandals) are OK, WV, WY and ND. Everything else is in play, including all the southern states.
He has a good chance in a few others (KY, SD, MT, NE, LA, TN and even AR, although I suspect they may want the "First Gentleman" on their side, after the election
). With the Deseret News editorial, he is in trouble in both UT and ID and, after "successfully" mobilizing "the blacks" and Latinos against him, GA, AZ and even TX, AL, MS and SC may be a stretch.
Amateur hour at the GOP!
