At this point Trump needs to be Trump. The Democrats have pulled out all the stops. Trump needs to stay strong, and determined, but keep his voice low and calm. His last debate performance had the perfect tone.
I thought his speech today was very good.
We had that in Maine with the LePage reelection - the Dems were virtue shaming him, demanding he apologize, demanding every Republican condemn him, and he stayed the course - and ended up getting more votes for Governor than anyone in Maine history.
