If there were walls around California and New York, people would be scaling the walls to leave the states… sort of like East Berlin.
If there were walls around Texas and Florida, people would be scaling the walls to get in… sort of like the US.
Do we really want dummycrats running the country as they do New York or California?
As a side note, East Berlin was an ecological disaster before the wall came down… sort of like China. West Berlin was a clean modern city. Now, the whole city is clean. Communism only works in the imagination of dummycrats.
