Even IF (and that is a mighty big IF) Chris Matthews "admits" Social Security is a Ponzi scheme - why would you think that what Chris Matthews says is gospel truth? It would be his opinion. His opinion does not make it fact.

Same way with Ricky Perry's opinion of climate change, Michelle Bachmann's opinion of no child being vaccinated by government rule or Ron Paul's opinion of anything not mentioned in the Constitution is illegal.

Opinion does not make something fact.
