The name is grimly fitting because in a sane political system he'd be a hardline, unbudgeable right-wing voter. I also think he's a useful reminder that "why won't the side I disagree with vote in muh Best Interests?" really isn't the rhetorical magic bullet everybody assumes it is, and is no substitute for voting based on sound moral principles.
Nah, you guys should have to keep him.
Anyway, I'm pretty ambivalent to NSV...not my cup of tea, but he can be funny at times. I tend to just assume his goal is to rile people up, and having regrettably engaged in that activity in the past, I'm not really in a place to hold that against him.
