im fine with republicans just pointedly not endorsing trump they arent gonna endorse biden openly. would be nice, but no active republican will do itI doubt that Romney is going to publicly endorse Joe Biden. Maybe, privately, Romney will vote for Biden but I think that Mitt will keep his vote secret and not publicly endorse anyone. He's obviously not voting for Trump though.
I think that he'll probably write his own name in, write-in John McCain or someone else lol.
