Collusion means joining together in violation of the public interest. If Trump’s brain comprehends only private interests, even a transaction in which Putin offered explicit help winning the election in return for Trump weakening NATO and giving Russia unfettered license in Ukraine wouldn’t be collusive.
When private deals are everything, the law is irrelevant. This also seems to fit with Trump’s worldview.
If he genuinely believes the hush money he had Cohen pay was a “simple private transaction,” Trump must not think the nation’s campaign finance laws apply to him. But if they don’t, why would laws and constitutional provisions barring collusion with foreign powers apply to him?
As we enter the third year of his presidency, Trump’s utter blindness to the public interest is a terrifying possibility. At least a scoundrel knows when he is doing bad things. A megalomaniac who only sees the art of the deal, doesn’t.
It gets even worse when one considers that Trump is, generally speaking, terrible at making deals.
