It's not about evidence. It never was.Thats not whay the OP is about. Its why do people not stop coddling this whiny child throwing a tantrum and instead tell him to shut up and own his defeat like a man. Thats what we whould all be doing, but a large chunk of the nation--including many Republican leaders--are playing along with this farce despite the fact the Toddler-in-Chief has no evidence to support his claims.
Whenever the actions of Trump or the Republican Party seem not to make sense on their face, I find it helpful to remember this statement:
Fascism seeks to maintain power regardless of political norms.
... and then their actions suddenly appear entirely consistent and logical.
