So Biden is an abuser — ­because women have accused him, and all women should be believed. Right?

So what has changed since then? Sexual assault and harassment are some of the most serious ­allegations that can be leveled against a man. Harris now needs to account for why she is comfortable joining an abuser’s 2020 ticket. This isn’t some ­debate-stage policy disagreement she can just walk back, claiming she has “evolved.”

There are only two possibilities. One is that Harris didn’t, in fact, believe Biden’s accusers but claimed she did to score political points against him. If so, she used the very serious issue of sexual assault as a cheap political cudgel.

The other possibility is that she still believes the ex-veep’s accusers but is comfortable teaming up with an abuser (not to mention a racist, another charged accusation Harris has thrown Biden’s way).
