For some reason Donald Trump can’t stop talking about “collusion.”

The president is notorious for his habit of projection. In his latest tweets from yesterday and this morning, he took this predilection to an extreme, angrily accusing both Hillary Clinton and Barack Obama of “collusion.”

In the case of Clinton, she’s apparently guilty of colluding with her own party:

With Obama, there is the murky suggestion that he colluded with the Russians by not doing to enough to stop Russian interference in the 2016 election:

Saying that Obama “colluded or obstructed” is almost too transparent in its desire to throw back at Democrats the same critiques that Trump is facing. At the risk of being banal, it has to be said that the DNC might have had their thumb on the scale for Hillary Clinton, but that is not collusion—it is favoritism. Similarly, Obama failing to prevent Russian interference in the election is not collusion.

It’s a sign of Trump’s desperation that he is waging war with the common meaning of words. To re-work an old saying: If the facts are against you, argue the law. If the law is against you, argue the facts. If the law and the facts are against you, pick a fight with the dictionary.
