Consider the possibility that the game here does not depend on Trump winning in the Electoral college- all that needs to happen is Biden not winning 271 or more EC votes for the congress to decide the presidency via the Contingent Election process outlined in article2, sec1 clause3 of the constitution, later modified in the 12th amendment.
In that scenario, each state delegation has 1 vote- and the GOP has enough state-level gerrymanders to control enough state delegations that if it comes to pass that the 12th Amendment process decides the presidency, they are very likely going to be able to install whoever they want.
If the smart money in the GOP has decided Trump won’t win but it still wants him in the oval, anything that prevents Biden from getting 270+ gets them better odds than any other pathway
