Well, let’s calculate how many electoral votes Buckwheat would win in California with district apportionment rather than winner take all. I would guess that it would be less than 54.
Do the same with Texas, Florida, North Carolina, Georgia and Virginia while you’re at it. There will be additional EV’s freed up for Democrats. Democrats have advocated such a move for years. It will have the effect of giving control over to large population centers, ie cities. This is something the Founders feared. Look at the Senate not just the Electoral College.
