Makes you wonder why Chuck Norris hasn't killed him yet.

There are many ways to successfully kill a president I'd imagine, but limited ways to do it without being caught. I guess if someone was really desperate they could hide a grenade up their ass and enter a public meeting near enough to the president (hey, I don't usually think like this- I blame the LVP community!)
