The bottom line … There are two forms of “collusion delusion”:

The Trump/Fox victory dance because no one new was indicted for collusion or corruption involving Russia — and therefore claims of “witch hunts” and innocence were vindicated.

The bitter reality that this probe has spawned many others stretching far beyond Russia — so it’s delusional to think it simply ends with no collusion.

Be smart: The new defining question for American politics is: Will Democrats demand the nation stick to historical norms of proper presidential behavior, or will Mueller’s revelations be the new standard?
