If Trump wins Dems will muddy the water and challenge the results for months guaranteed. While they scheme and ballot harvest and try to rig the outcome.
If Trump wins, he wins. Who gives a shit what the Dems do?
Likewise, if Biden wins, he wins.
But Trump is already calling into question the legitimacy of the election by whining about mail in votes. And his mindless drone worshippers are posting everything he says like it's been anointed by God from above.
