What makes me think he won't try to reinterpret the Constitution? A couple of things ease my fears on this.
First, the things one must do to be elected President as a GOP candidate are different than the things one must do to be elected GOP mayor of NY. I know that's totally pragmatic, but it gives me reason to believe Rudy's recent shift to the right.
Second, Rudy recently stated that he likes the kinds of SC judges appointed by Bush. This, coupled with some of his other recent comments, give me some reason to believe he won't be a gun grabber once in office.
I know there's a risk. It's possible he could prove me wrong. But America (and the Congress) is not in a gun grabbing mood these days. It's not really a winning issue.
All in all, these factors (and others related to his positions on the war) lead me to say that if Rudy got the nomination, I'd have to support him against virtually any Democrat. That's just me. And I am a gun owner.
Just to clarify.... I'm not a one-issue voter -- there are a whole boatload of reasons why I don't trust this guy and wouldn't vote for him. The RKBA issue is merely one of them.
