If this entire situation were flipped, would you still be upset? Say, had Biden been winning on election night and the Democrats winning all toss-up House seats, but suddenly Trump had millions of fake votes at 4 in the morning, wouldn’t that anger you? If you say yes, but think Trump shouldn’t be able to challenge this, then you’re a partisan hack. Cheating is bad no matter who does it, and letting it slide is an awful precedent. Harry Reid got got rid of needing a supermajority in the Senate to elect judges in 2013, and that ended up turning on the Democrats when it came the the Supreme Court justices Trump was able to put in.
