I genuinely don't think this shooting will help Trump in November

Current Events

The media is reporting the shooter was a Republican, so yeah, I'd expect them to actually try and move on from this very quickly, since they stand to lose more from the potential bad rhetoric there than they'd gain from trying to make Trump look like a hero to the base who was already voting him, regardless.
