I mean...they should all be willing to work with Trump he he's actually going to do something good. I don't really think that's happened thus far, and hopefully he'll lose the election so it will be irrelevant anyways.
Why would you want them to refuse to work with Trump wholesale? They'd be no better than the Republican party, and realistically given Trump's history (and how much more unhinged he would be during a second term when he's got nothing to lose politically), it's not going to be relevant anyways. But in the off chance that Trump, say, pushes for something universally agreed upon as good like a sudden expansion of social safety nets, I'd want Democrats working with him to make that expansion the best it possibly can be.
