There is a good article at The Resurgent, “Trump Will Disappoint Everyone.”
Excerpt from the gun stuff:
“… Trump got an early endorsement from the NRA and is widely seen as a friend to gun owners. But in reality, it’s not a terribly high priority for him … Speeding up background checks, holding the line on awful “no fly no buy” laws, and generally supporting self-defense use of firearms is about the best we can hope for, and most of that is through the courts and congress. It’s not going to be a high priority–but hooray: it’s not Hillary …”
I can see Trump signing the reciprocity bill as payback for the endorsement, but that will require him and Mitch McConnell standing up to Chuck Schumer. I don’t see him going all out for suppressors and definitely not attacking the Hughes Amendment.
