The four Democrats in the Senate (Max Baucus, Mark Begich, Mark Pryor, and Heidi Heitkamp) who voted against background checks in the gun bill in the Senate explain why.
It’s pretty much what you’d expect: either they’re up for a tough re-election fight next year and they’re afraid of the NRA. One — Mark Begich of Alaska — mumbled something about not wanting to get caught up in an “an emotional moment” (where was this guy when the Senate whooped through the USA PATRIOT Act?).
But noticeably, none of the reasons have anything to do with actually doing something about gun violence.
