That was pointed out by the commentators today, Trump also claimed to have been cheated by a corrupt election system during vote tallies with Hillary Clinton. Until he won, then there there was no irregularities! Lying to get his way is just the Trump MO.
Just like how the Conservashits in this board post ridiculous shit they know is false and try and guess how they're going to be called out. Trying too set expectations so they can get away with being asshats
