I think it’s rather more that it’s painfully clear to anyone with a functioning brain that Donald Trump and his campaign is once again trying to manipulatively present himself as in more danger than he actually is and falsely blaming Democrats for violent vitriol. Donald Trump is firmly the one producing all the violent rhetoric in this campaign. The worst the Democrats have done is imply that JD Vance fucked a couch, and when they did, it was clearly in jest and not serious. Yet he turns it around and blames it on the Harris campaign immediately.
So, let’s go over. What makes this a nothingburger compared to what Trump makes it out to be:
This guy who they caught with the guns previously voted for Trump, and had also previously supported Vivek, after he was disillusioned with Trump. He’s clearly not well, but he’s also clearly not a true and blue progressive who was pushed to violence by evil Democrats being mean to Donald Trump.
Trump was never actually in any serious danger, probably because due to the previous massive fuckup the Secret Service is probably actually doing their job this time around. Since he was never in actual serious danger, because they were doing their job, it’s as much of a nothingburger as the number of times that such a thing has happened to sitting Presidents. It doesn’t blow up the news because it’s stupid when they’ve already failed.
