99% of what happens in Washington is talk, posturing and rhetoric. Evidence can be seen in the number of bills introduced versus those actually signed into law.
One month ago a SW MP Sport II was $504 at Buds. Today it is $549. Pretty good indicator demand went up caused both by the shooting and the talk afterwards. I think Pres helped create the market bump by talking, that's what he's always done. Compare the industry and politics during AWB in 90's versus today and you'll see even SW won't do now what they did then.
While that's true, it all goes out the window when it comes to guns because the Republicans know that even if they vote anti gun, pro 2A people will still vote for them over a Democrat, which is so far left that they don't even acknowledge an individuals right to own firearms for self defense, even though SCOTUS has ruled that's what the 2nd Amendment was created for.
Step 2 in Art of the Deal is "Protect the Downside" and making the statement of "seizure, then due process" and age restrictions without due process... all that is blatantly unconstitutional, no court would ever uphold that. If that language is in a bill that becomes law, the whole law will be thrown out.
We know Trump plays both sides because it's his business strategy. Step 3 is "Maximize your options" so he's trying to play the center and, what I think he's going to try to do in the future, is either get some pro-gun stuff into this bill or have it be nothing but anti-gun, watch Congress flail about and not pass it, then after the bill fails and the media declare that no child is safe and the sky is falling, have another bill be introduced that is a compromise bill.
Bump stocks are gonna go, whether they're at the state level or federally. The thing is if both sides can go into an election saying they saved the children and had to also include national reciprocity to do that, hey at least they saved children. Swamp Creatures get re-elected and the Swamp Creatures love getting re-elected.
What Trump's already done in signaling anti-gun stuff is he's doing Step 4 "Use your leverage."
Trump is president, he ran on a pro-gun platform. By all means, he could be the most pro gun president since Calvin Coolidge, but he's signaling gun control because the NRA is so close to him and we know that gun industry is struggling for sales right now, Trump saying such things is increasing prices. That's by design and I wouldn't doubt it if the NRA told Trump to say stuff to Republicans about being afraid of the NRA and denial of due process to induce some panic buying.
Trump's is a business man, if all it takes is a few sentences to generate some profits for a struggling industry that supports him, he'll gladly do it because in 2020 he'll get some nice campaign contributions.
All politics is Rope-a-Dope and I don't know what the future will bring, but the simple answer is that if Trump is genuine in what he said this week in that live meeting, we're all in big trouble because we have a President who would throw the entire populace into internment camps to "keep us safe."
