I believe they are going after the low-hanging fruit, first. The states where it was the most blatant and the easiest to prove. Once they have secured Trump's reelection, then they go after them all. Muahahahahaha

I also believe this is why there is a two pronged approach. Trump's team is mostly arguing constitutional law while Sidney and Lin are arguing rampant fraud, Dominion, etc. (Obviously there is some crossover). The constitutional law approach is the quickest and easiest way to get to 270. Once Trump is reelected, we have all the time in the world to nail every single one of these bastards to the wall.
