The best evidence in political science seems to suggest that women do *not* face an electoral penalty.
But isn't the idea that America is so sexist that women do face such a penalty the more "woke" position?
"Women do face an electoral penalty." Sexist!
"Women don't face an electoral penalty." You're blind to sexism!
There's a difference between
1) "It's terrible women are penalized" and
2) "Women are penalized, so you should let me run"
But isn't it likely that Sanders meant 1) but Warren (reasonably) heard 2)?
So still a silly debate.
