It's a joke. He is referring to the Liberals wish for an actual working(thriving,high standard of living, etc..) Solialist/Communist country to point to and say, "Look at how great they are doing, lets try that". And to the fact that the Libs hate Reagan for bringing down the Soviet Union.
Really? I'm not so sure, as the piece is sloppily-written, such as in, "Bush 1st should have taken out Hussein in '91."
