I feel old to have lived through Virginia’s transition from ancestral Democrat to Republican dominance to, finally, moderate-to-liberal metropolitan Democrat.
Virginia was the first southern state to make this change. May Georgia, North Carolina, and Texas he close behind. (I can’t think of any other comparable southern state.)
Might happen in South Carolina long-term as well.
That would surprise me as South Carolina lacks the very large city / tech hubs you need to trend D with a Trumpish GOP. It's still too rural, too many retirees, small-city conservative, Evangelical.
