Actually, due to a 2020 U.S. Supreme Court case, if a state has a “faithless elector” clause, the electors CANNOT vote for anybody but President Trump or Joe Biden, unless the Green or Libertarian candidate wins in that state/congressional district. This was a rare “bipartisan” Supreme Court vote. Unanimous, although Justice Thomas wrote a separate opinion. 32 states have such laws.
I thought, and I could well be wrong, that the SCOTUS ruled that states could, if they wished punish ‘faithless electors’, but didn’t require that they do so. I seriously doubt that democrat states would punish Electors who voted for Biden’s replacement. Kind of like not electing to punish ‘mostly peaceful’ protestors for burning down a couple of buildings.
