Rudy in New York is NOT Rudy in DC. In NY guns is one thing - at the national level, with the whole of the country at bear - something else intirely. He will NOT move against guns spontaneously at the very least, and he may well not oppose pro-gun moves.
THIS is a huge net gain compared to hillary KFC clinton...
Rudy has already attacked the Second-Amendment rights of everyone nationwide. What makes you think he won't do so again if given the chance?
Put it in writing.
