I believe Giuliani will say "what I promoted for NYC is not what I promote for the rest of America". I don't believe he will make it an issue. Nobody has made it an issue since it cost Al Gore the election in 2000. The Democrats aren't even pushing it now that they have control of Congress. They know its a losing issue.
Please ping me the instant he does (I'm serious). I would like to think at the very least that he can look at these issues a bit more seriously than he did in NYC. It's easy and a cop-out to target law abiding gun owners the way those lawsuits did.
