Yes, but it's a common litmus test issue for us righties.
Yeah, I don't think liberal gun owners are usually as worried about restrictions, anecdotally. I grew up in a relatively apolitical hunting family, and I don't think they really pay attention to gun restrictions. I dated a left-wing very serious gun owner (had antiques, owned 20+ pieces, gave demonstrations, hunted, bowhunted, went to the range, etc) who actively voted AGAINST the IRA at every opportunity. Then I have some right-wing friends who don't carry or even own, but to whom it's still a litmus test of candidates.
I wonder if gay marriage tolerance is a similar lefty litmus test. Like, I have no intention of ever marrying a fellow woman, but if a candidate devotes energy to opposing it, they're more or less out of the running in my book.
