It's always interesting to me when I see someone defend socialism by first denying that something isn't really socialist.  But if it WERE socialism, then it's still ok.  Socialism as with communism has historically taken on many forms and flavors depending on the country and the time period.  On top of that, Sanders has not provided detailed information about how he plans to pay for the things he's promising.  He doesn't seem to be uncomfortable with the socialist label  so I say call him a socialist!
