This was always the simplest and most obvious point Trump had. In many states, election processes have been changed by governor, or even course, bureaucratic or court fiat. This is clearly wrong.
The stuff about “the Kraken” or China or Venezuela will be extremely difficult to prove. But its clear beyond a doubt many states are running un-constitutional elections.
The election processes being unlawfully and unilaterally changed in many states (including PA, WI, MI, GA and others) outside of the legislative process was the obvious path to victory here.
Why on earth didn’t those representing the Trump campaign focus on those issues? That was the most likely path as existing state laws were violated in multiple cases.
