Giuliani's statements along these lines are nothing more than a pathetic attempt to cover up his track record when he was mayor of New York. Back then, he specifically DID NOT view gun control as a "state and local concern" -- as evidenced by his numerous calls for the Federal government to enact Federal gun control laws similar to New York's (plus his abuse of the Federal court system in filing frivolous lawsuits against gun manufacturers in other jurisdictions).
gun banner == liberal. Surest way to figure out the mystery.
