In terms of the election itself, probably not.

Well deserved sarcasm))) But speaking about South - IMHO, rapidly developing more urban (especially - with large metropolitan areas) states generally either move Democratic or "stay put" now: Virginia, Texas, Georgia, North Carolina, Florida. More rural, lacking really BIG metropolitan areas - generally continue to move Republican with varying speed: Tennessee, South Carolina and especially "last four": Alabama, Arkansas, Louisiana and Mississippi. For example - i expect strengthening of Republican positions in two last state's legislatures, as "last white Democrats" (able to win Republican-leaning seats, and, usually, with at least some conservative inclinations), first elected 15-20 years ago, generally retire, and are replaced by Republicans, while Democrats have very little targets there (the majority Black seats are already Black Democratic, and majority white - basically unwinnable).
