Trump's participation in the process isn't required. Heck, everyone is probably better off if he isn't involved.
Imo that's more a question for the gop politicans. McConnell had an antipathy for Obama, and it was personal, not race. It's a lot different with him and Biden. But Moscow Mitch was never just a Trump syncophant who suddenly went all in for Trump's divisive bs lies about fraud and corruption, even after accusing him of that themselves. Brave Brave Sir Lindsey and Ted, the Son of the Kennedy Assassinator. Imo it's beyond time for these assholes to start saying, "Trump wants recounts, he should get them where states say he should, but there's no evidence of all this fraud, and if Trump has some, he should put it up or shut up"
A lot depends on the gop's new Courts too. If they leave Texas and Ga's moves to restrict voting but don't allow states like Pa to expand voting .... not so good.
With gop voters, Trump actually under performed senate candidates in Ga, Az, Tx, NC, Co, but that's probably not true everywhere. I'm not comparing progressives to white supremacists morally, but the dems have to accomodate people saying defund police and the gop will have to accomodate people from the Trump base.
