We should be thanking Trump.  For two reasons:
1.  He snapped the political establishment into looking at the needs and concerns of a lot of citizens who were being left out of the conversation.  That was overdue.
2.  He's created an uprising that's going to wash through local and state houses, as well as governorships, just in time for the decadal redistricting.  Republicans have won the redistricting battle which allowed them to gerrymander congress.  That's going to be reversed in 2020.  Republicans in congress are terrified about what's coming at them.

Sometime a good enema is required to flush out the system.  Trump is that enema.
