If that were coming, it would've happened already, IMO. For weeks now, Warren's official campaign strategy has been "stay alive until a hopefully-contested convention and then get nominated as the long-shot Party Unity candidate." She hasn't won states or delegates, but that's not part of the plan any more anyway.

I'd say that the main difference is between 'difficult' and 'cannot'. Hillary won the popular vote, and lost the electoral vote by narrow margins (10k in MI).

And the electoral landscape has changed dramatically in 4 years. The claim "a woman cannot win in 2020" is a misguided political judgement. It's not a statement of value.

Not to diminish the complaints, or excuse his actions, but I don't think a journalist would say that Biden has numerous sexual harassment allegations against him. One can say that Trump has numerous sexual harassment allegations against him. How do we draw a difference?

Some journalists already have

I do think that believing that a woman cannot win the Presidency is both a character flaw and misguided political judgement.

Genuine question: what's the difference between Bernie theoretically saying "a woman can't win in 2020" and my sister, a Warren supporter, saying "it's much more difficult for a woman to get elected than a man"? Take the latter statement, add the fact that winning in 2020 will be difficult for any Democrat, and the logical conclusion is "it would be incredibly difficult (impossible?) for a woman to win in 2020."

Does Biden have numerous sexual harassment allegations against him?

See the Vox article I linked above.

I don't take the fact that Bernie told Warren that a woman can't win the presidency to mean that he isn't a good person either. These are character flaws.

Even if you believe that Bernie said a woman can't win, that's not a character flaw, it's at worst a misguided political judgment. There's a huge difference between "a woman cannot win this election" and "a woman should not be able to win this election." Do I agree that a woman can't win the election? No. Do I think it would be more difficult for a woman than for a man? Absolutely. Equivocating numerous sexual harassment allegations with a single alleged misguided political judgment is laughable. The degrees of harm really do matter.
