Although there are some groups within the liberal coalition that just vote D no matter what (most blacks)
I believe most of the rest truly believe in socialism/communism
Until we prove to nearly everyone that socialism/communism doesn’t work we wont be able to move forward.
There is an old saying: “You can vote yourself into socialism BUT you have to shoot your way out.” I think Venezuela is a good and current example.
I believe the radical left took over the democrat party in the 1964 and 1968 elections. Now the radical left is just pure socialism and they don’t even care to hide it, with a complicit media.
