The Dem Party is hostage to their Far Left Wing and that’s who they are pandering to.................
It only makes sense to pander to an isolated part of the political body if that small portion is yielding some type of return.
Is it electoral? Yes. The far left cheats on behalf of the Dim party.
Is it political? Yes. The far left funds the Dim party.
Is it personal? Yes. The far left lauds Chuckie and his kind for being leftist douchebags (they love and applaud this sort of thing)
So Chuckie is acting rational, if contrary to the will of the people.
OTOH, it shows how isolated the Left is within its MSM, Big Education, Deep State echo-chamber.
