The strategists at Camp Biden know that with millions of new gun owners out there, and the progressives of their own party calling to abolish cops, the standard "you dont' need to own guns, only savages and bunker-dwellers do that, just leave it to the cops" message is a non-starter. People who'd normally never own guns or think about owning them now DO own them, and the usual canned-ads about "Gun ownership violent and wrong" that they'd have never noticed or nodded in approval of 4 years ago, now will turn them against the Party as the last thing they want upon finally getting self-protection is being told "Now hand it back".
Note that while the media deployed their standard ISO-9000 lie that Rittenhouse had an "assault weapon' , they didn't call for more gun laws or background checks or bans or whatever, because even THEY know that trying that angle is a losing prospect when, thanks to the clusterfuck people like Wheeler and Lightfoot have made of their cities, the "that'll never happen" scenario of the anti-2A crowd, a defense against mass civil unrest the cops can't stop, CAME TRUE.
Trump doesn't have to say it because he doesn't have to, until/unless Joe has a senile moment and blurts it out during debates...
Gun control, for once, isn't even a top ten issue for voters
It's dead for the next 20 years at least.... maybe longer, as long as there are vivid living memories of plague and riot, the "do you really need a gun?" soft approach is not going to work, let alone "Turn them in or else, we know what's best!" from the same governments whose own incompetence caused those problems.
