Trump advisor says states are preparing slates of alternative electors
I'm not sure how much of a formal status these alternate slates of electors will actually have. I believe, under the Constitution, Congress will need to decide which slates to accept on January 6th or thereabouts; or possibly the state legislatures can officially switch between them. Suffice it to say this is mostly Trump's legal and political team preserving their options to contest the election. It should not be read as changing any outcomes.
