So far am not convinced the shooter had any 'political' motivation at all. I note it's been reported that his father owned at least 20 guns, though.
Agreed. But, I don't think we can discount the gun culture the Republicans push and the easy access to things like his AR-15.
I have a crazy theory. What if he did all this to prove to his friends who told him he was a bad shot, that he was actually a good shot. And shooting the president would be a grand way to do that. How crazy would that be?
