On the other hand, I think it's been amazingly notable over their years how lockstep the voting has been on the Democrat side, while the Republican side has seemed much more comfortable with diversity of thought.
I don't know what the lesson there is. Maybe don't judge books by covers? Maybe it's more about the people who elect the different parties? Maybe some sort of statistical averaging? Not sure.
But watching Democrats vote in lockstep this week has really driven that observation home.
