This will continue until someone finds a way to reconcile the two major groups who currently call themselves Democrats: the not-very-left centrist and the very-left social-progressive. (My terms for simplicity)
The centrists appear to fear the social progressives and the progressives seem frustrated with the centrists. These groups really need their own parties, but that’s political suicide in the current electoral model.
I’ll buy it. ILY is taught as a gesture to lots of kids these days. Every kid I know knows it.
