Funny, you have now moved the goal posts from "forced" to "she feels pressured" without a single admission that you used the wrong word.
Look, I recognize that it's a weak endorsement, I'm not pretending it is something it's not. But, by definition, it's an endorsement; she publicly stated who she is voting for, revealing that she thinks the best way to cast her vote at this point is for harris. You just don't want to accept the definition of word of "endorsement" and now "forced." Endorsement doesn't mean you're over the moon ecstatic about the candidate. Plenty of right wings and conservatives have endorsed Harris, not because they agree with her policies but that they recognize what a disaster trump is for the country.
All it means is that you publicly show your support for a candidate...which she literally did by publicly saying she would vote for Harris.
