‘It is not impossible but it is very very unusual.’
electoral politics will be very very unusual going forward; when the aging white population passes away, and their progeny finds itself in minority voting status...there will be fracturing in party loyalties, less adherence to party interest, and the desire by the populace to be beholden to nobody...
the political philosophy that cannot adapt will die an ugly death...
Your analysis is wild speculation without hard core detailed analysis of voting numbers by city and county.
Political science, yo!
