Senility didn't cause this problem; the blood clot was in the brain and according to Graham, McCain had recently started having trouble speaking and not being able to remember. This is likely to be labeled a stroke.
It sounded to me that the other poster wanted him out just because he was old. What age is old?
He has had trouble remembering he is supposed to be a conservative and a republican off and on for a while.
I am not down on him for his age--my parents are in their 80s and doing well, my grandmother didn't start to lose it until her mid 90s, the other until nearly 100 (she lived to 101). I fully respect, perhaps more than I should according to some sources, his military service and time in the Hilton in Hanoi.
That said, I, like many posters here, find his tendency to side with the Democrats on some issues to be a disturbing trait that might be explained by cerebrovascular events rather than plain old crypto-liberalism. If brain damage, even transient cognitive malfunctions are related to organic processes and not simply faulty character and logic, then he either needs to address the health issues more fully, or, if they cannot be addressed adequately, should consider resignation. You wouldn't want someone who isn't fully in command of their faculties driving a truck, driving a country affects far more people.
