Now if the Republicans run Trump in 2024, we’ll probably get another exception to the R-D-R-D etc. habit. 2/3rds of all Americans don’t want another Trump vs. Biden matchup in 2024.
To the point where one more "exception" and suddenly your "rule" is no longer a rule anymore.
By the way, if enough state houses grant themselves the power to just overturn state vote tallies on a whim, there won't BE two major parties anymore.
I guess you're just focused on the horse race aspects of it and not the consequences of a series of failed constitutional crises.
