I don’t think the Republicans have completely thought through their attempts at a Supreme Court case to address perceived election system wrongs. If it were to have gone to the court, there’s a whole lot of stuff in that pandora’s box, a whole bunch of unintended consequences. Andrew McCarthy at the the National Review provides a reasonable take:
“What this argument implies, whether the states making it realize it or not, is that even if Missouri wants to apply its own, stricter voter-identification standards, California should be allowed to file a complaint against Missouri in the Supreme Court. After all, the uber-progressive Golden State’s experts will say a strict-identification requirement disproportionately discourages qualified minority voters, which depresses Democratic Party turnout, effectively inflating the value of Republican votes to the detriment of Californians, who voted overwhelmingly for the Democratic candidate.
You can see where this goes.”
