Its the way they have been false portrayed by the NRA and the right wing. They are, and should be for sensible gun control. Hearing this makes me more inclined the vote for Montgomery as I can't stand the NRA. I think Democrats should move more to the right on abortion, not gun control.
I was referring to the push in the early/mid '90s to ban civilian rifles with protruding handgrips, shotguns holding more than 5 shells, and rifles and pistols holding more than 6 or 10 rounds, as well as a handful of other guns that the prohibitionists don't like. S.1431/H.R.2038 (2004 session) would have even banned my Ruger mini-14, by name:

The ban-nonhunting-guns position wasn't a leftist position, it was a
DLC position. The Democratic left has historically been neutral on guns, and it was the DLC, not the left, that spearheaded the push for sweeping bans on nonhunting guns in the early to mid 1990's, and thereby helped cost Dems the House, the Senate, and two presidencies.
Dropping those bans is merely returning to the traditional Democratic position on the issue, and IMHO is a major reason why a lot of swing voters in pro-gun states are feeling more comfortable with national Dems since '04, as you're now seeing in the polls.
