Donald Trump stated back in 2012 that the Electoral College was a disaster for America and that it should be changed, but he sure loved it when it helped him win the election in 2016. Classic Trumping.

shitting your pants and then walking around and denying that you shit your pants even though everyone can clearly tell that you shit your pants, and if anyone accuses you of shitting your pants, you tell them that in fact THEY shit your pants and that this part of some conspiracy against you to fill your pants with shit even though you're simultaneously claiming that there is in fact no shit in your pants. Then, out of misplaced loyalty, about 1/3rd of people convince themselves that somehow you're not obviously lying to everyone and so you then tell these foolish people that it's actually chocolate in your pants and then make them eat your shit in front of you
Person one: what the fuck is that smell?
