Sen. as in senile.

If you're wondering just how much these Republicans really care about the future of the United States keep in mind that John McCain is seeking his 6th term in the Senate. Never mind that he is nearly 80 years old and unable to provide a sharp focus when needed. Never mind that he made one of the biggest blunders in political history when he chose the vapid Sarah Palin as a running mate. Forget the fact that he is often forgetful, petulant, overly hawkish, and excessively belligerent. He doesn't really care what's good for Arizona, just what suits him. His ego demands that he win another term as Senator and to hell with what's best for Arizona or the country. Of course he's been coasting on that prisoner-of-war legend for most of his career. I guess he thinks that's enough of an entitlement. Maybe for most people, it is.
