Most of what I see on twitter from the new right implies if not hypothesizes intent. Most of what I see from the new left are attempts to excommunicate the shooter from the party (as if that matters), avoid party blame, and at best bite their tongue through Trump's status come up. Most of what I see from moderates is disgust at the incompetence.

All things considered, it feels like intentional incompetence to me but hopefully we eventually get evidence to suggest otherwise.
