Most polls are showing that attitudes on both sides are hardening, with almost no folks in the middle with neutral or "I have an open mind" opinions regarding either Trump or the fevered "resistance".
As one who loves engaging folks in political discussions on the train to work, I've noticed that dialogue with the Trump haters is getting increasingly impossible. They get flustered and apologize that they just cannot continue the discussion. I've seen their eyes well up with tears at the rage and dislocation they feel. It is, to be perfectly honest, scary to see the country this polarized and unwilling to dialogue.
