They're shedding people. Slowly.
We don't like whites.
We don't like men.
We don't like CIS.
We don't like Asians.
We don't like Christians.
We don't like Jews.
We don't like Blue Collar.
We don't like... after a while. They're going to wonder what happened to their votes.
I remember before the 2016 election season, Michael Smirconish lecturing Republicans about widening their tent beyond whites because of projections that in a couple of decades, whites will no longer be a majority. Patiently waiting for him to lecture the progressives to stop shrinking theirs.
