I’ll note that the NYT changed the headline from
Harris Reiterates Support for Ending Filibuster to Protect Aboriton Rights
to
Manchin Won’t Endorse Harris After Her Call to End Filibuster Over Abortion Rights
An archived copy of the article from before the change emphasizes her position, rather than the opposition from Manchin.
Well, as she’ll (hopefully) be president, she can exercise her right to veto.
It could go either way, but reasonable point. We will see.
