Good grief. Politicians will say anything to get elected, unless they have real bedrock principles, like Reagan or Goldwater. You should look instead at Rudy's track record, which is very liberal, not what even a middle-of-the-road Rupublican would support.
His track record in NYC is fantastic, in case you want to check out what he did there. The libs hated him while he was mayor. Nuff' said about that.
