Republics have fallen before. Rome went from a republic to a military dictatorship dressed up with republican, monarchical, and religious decorations. The people who brought that about were the same sort of people the Democrats are. Unless Republicans hold them in check, it
will happen here. And Republicans won't be able to do squat without appealing to non-white voters because of demographics. And keeping Lott will throw away any chance of getting a decent proportion of those votes before it's too late.
A thousand years is optimistic, BTW. It was much longer between the fall of the Roman Republic and 1776.
You're being melodramatic. And, you're not a seer.
