Personally, I thought they should have pursued this more aggressively before the election, until waiting until afterward when it was too late.
I still think that if Trump had won, the Dems would have raised many of the same objections Trump's team did. The main difference is the news media wouldn't have refused to cover it, they would have been shouting it from the rooftops, and Big Tech wouldn't have been squashing all talk of election fraud. The Dems probably would have blamed the whole thing on Russian interference, and probably would have impeached Trump for it two or three times lol.
