If the Republicans select a Speaker of the U.S. House of Representatives with a pair, all of this will get investigated, AND they can refuse to recognize the election results from a fraudulent election, and refuse to seat Congresscritters from these districts.
I think Detroit is down to at most two congresscritters, and while I have no doubt that they did win, running up the score unnecessarily for the sake of influencing statewide races seems a good reason for penalizing the district(s) until they clean up their acts.
