Well the election laws primarily come from the election clause of the constitution. So that couldn't be changed without an amendment requiring a super majority, which neither party will get. What I assume he is trying to do though, is while having state leaders being majority Republican, have the states update their election laws, because that's who controls the elections. (Unless the supreme Court blocks it, as we saw with Colorado). Also held by the Republicans.
I assume his attempts are to lock all the states currently red, red. Is it possible, doubtful. As states also may require super majoritys to update their election processes, but that may vary drastically by state. Shit one state was discussing getting rid of popular vote all together and just allowing their representatives to vote leading up to the election.
The country we knew as the U.S. is broken. Only threads to hold it together now
They don't care what the content or format is, just who owns it, and where the data is flowing. They want the data flowing into the U.S. and sold out. Rather than into China and sold out. That's all it is.
