Trump is not playing 3-D chess here. He was probably just watching Tucker Carlson on DVR, and being plunged on tape delay into the same rage that Carlson had stoked in real-time in the angry old men who watch him live.
Plan or no plan, though, Trump hit the Democratic Party at its point of vulnerability. He is driving it toward ever more radical outcomes: against enforcement of immigration laws and for the acceptance of virtually all border-crossers; against the bread-and-butter issues that will mobilize the voters the Democrats need and for the symbolic actions that will gratify the educated urban progressives who live in the safest Democratic districts in the country.
Pelosi has been right at every move of this game. She is working to replace Trump at the ballot box, and she is working as best she can from the House to avoid mistakes that will help him and hurt the eventual Democratic presidential nominee.
Most of Pelosi’s party may well know and agree she is right. But knowing and doing are two very different things.
