current theory is that the republicans want trump to help them in the GA runoff elections, and in order to do that, they need to placate him about this voter fraud because without trump and trump voters in GA, they lose the senate too.
but man, thats a dangerous game. its wildly irresponsible.
i also don't see trump having a bigger effect than he already had/has.
but republicans gonna republican. totally cool with ruining american institutions if it gains them anything at all politically.
