I listen to Levin very little, but do specifically remember him ranting that we could lose both the House and Senate because of Trump being the Republican nominee. I doubt he’s ever gone back and admitted being wrong about that.
I listen to Levin every day and he supported Trump months before the election. He does call out Trump for positions he disagrees with, like increasing ethanol subsidies, or the tariffs. But other than certain items he is a huge Trump supporter. Levin attended the Jerusalem event for the move. There is nothing wrong with not being a rubber stamp.
