Frankly I’d tend to agree, it doesn’t seem likely there’d be a lot of them exactly because… well, gestures around broadly
But now that I think about this, even though the effect on swing voters could well be pretty inconsequential, the shooting might well “reactivate” some Republicans who weren’t necessarily going to vote – although I’ve understood that their turnout is often a higher than the Dems’, it’s still not 100%. Now whether that is likely or what the size of the effect could be isn’t something I’m really qualified to speculate on, I’m just a random Yuropean who woke up this morning to find that while I was sleeping somebody apparently tried to murk Trump.
