An alternate group of electors are voting. That way if the court cases we send that never see the light of day due to corrupt judges happen to magically go through and end up our way... we can send this to the democrat led house who impeached the president based on no standing outside than the fact they didn't want him in office. They'll just be fine with this and this strategy is flawless.

There's a difference between this title implication of "The contested states have sent alternate electors" and a theoretical response to "what would stop that?" question in an interview.
