You may be right, but if the individuals you named rule as you suggest: 1 Leftist for RKBA, and one nominal conservative against RKBA, that still equals 4-4, with Kennedy as the swing vote. I would rather not have to fret about it.
No, no, I’m not saying I think that’s how I think they’re going to vote, I’m saying I don’t think it’s one of those frequent situations where eight votes are known, and you just have to wait to see how the swing vote or two is cast. And I agree with you. I was hoping for at least one more libertarian/originalist, preferably replacing one of the far left-wingers, before I’d be comfortable.
