By November 2020 Democrats hopefully won't have to care about Moscow Mitch at all, but in the here and now I'll gladly and excitedly take any gun control measure that passes Congress that intends to prevent the loss of further life, yes.
On the broader point though, for years, if not decades, Democrats have argued consistently we're not going to come to take away your guns like the Republicans are claiming we would, instead saying we support sensible gun control measures to curb the gun violence epidemic. That's in part what has led to winning suburban voters over as mass and school shootings are becoming an increasingly frequent occurrence, opening the path to actually be able to pass laws like the assault weapons ban we know work. The NRA is a shell of its former self because the positions of the NRA and Republicans are increasingly seen as extreme. The one way to lose suburban voters again, to lose this momentum, to give the NRA a new lease on life and boost rural Trump voter turnout in 2020, is to say you support mandatory gun buy-backs.
When he says Democrats shouldn't worry about Republicans but go out there and run on the right policy, I don't think he means they should go out there and support a dumb policy.
I'm not as on board with this as I once was because we can't look at these policies divorced from reality. And the reality is there is a rise in killings associated with a specific type of gun. And nobody's safe from this. This isn't about gun violence happening in the hood. This isn't even about American citizens being able to arm themselves. This is about the fact that everyone's kids, even lily white ones, are having to go to schools and do drills to better their chances of survival against a white supremacist wielding a specific type of gun. That when people going to public events and public spaces express fear of a mass violent act, it's with a specific type of weapon.
So while I understand not lending ourselves to Republican talking points, I do think we need to stop doing that to the point that we care more about not getting their voters than losing ours. Americans are afraid of the AR-15. Suburban white voters are afraid of the AR-15. Any voter who would think Democrats saying "We're going to ban those types of guns" means "We are going to take away all guns" especially out of the mouth of a Democrat from Texas was always going to fall the Republican talking point that Democrats are going to "take yer gunz." And they're just not worth it. They're not worth losing the energy of our base over.
We've had an assault weapons ban before.
