@MontereyJack,
That is incorrect. My 20 year prediction is merely a prediction. Let's compare notes after election day 2032 and see if I'm right.
And no. There is no gerrymandering in Senate races or presidential races.
Senate races are decided by the total vote of an entire state
with no subdivisions.
Except for Nebraska and Maine (neither of which have gerrymandered congressional districts), presidential races are decided by the total vote of an entire state
with no subdivisions.
