Rhetorical 'ism' (socialism, communism, marxism) name calling turns a lot of people off and they then tune out whatever message they might otherwise hear.
People are waking up to the reality of obama, Reid and Pelousy and the polls show increasing disapproval and anger.
Give voters the facts and some conservative opinions and they will come up with their own 'isms' about obama.
To mock by using phrases like "The People's Republic of San Francisco" carries no weight with young people because the listener has no context, only the words. "What's wrong with a 'peoples' republic'?" I was asked by a puzzled young colege graduate last week. He was unaware that violent communist regimes had a special affection for that terminology.
"Socialism" is pretty much the same thing: It works well when preaching to the choir, but leaves the uneducated young leftist confused and assuming the speaker is bitter about some bad experience in the distant past.
