Guys, I hate to be controversial here, but maybe we can't extrapolate anything valuable about politicians based on two incidents of attempted assassination. I don't care about the opinions of these two crazy guys.
If it becomes a democratic majority of the US who has attempted to assassinate the guy, it would be right to listen to them about who should be president. But not because of the assassination thing.
The two people are just two people, as you say. What we're actually talking about is how thousands of relatively famous Republicans and tens of millions of other Republicans react to the actions of those two.
