This is why Trump’s decision this week to throw Sen. Mitch Mc­Connell and Speaker Paul Ryan under the bus was greeted with such glee by many Trump boosters. They place the blame for all of Trump’s myriad blunders on the GOP “establishment.”

They’d rather see Trump pivot and work with Democrats if it means Trump can declare victory about something — anything — and if it makes the establishment look bad. What was once a fear is now a hope.

The problem is there’s another reason Congress has disappointed the president and his most ardent supporters: Donald Trump doesn’t know what he’s doing.
