Speaking about Russia's invasion of Georgia, John McCain actually said:

In the 21st century, nations don't invade other nations.

Umm John, have you forgotten 2003? That's not a rhetorical question - the earliest symptom of Alzheimer's is the loss of recent memories.

Has early Alzheimer's caused McCain to forget 2003? Add this "lost memory" to McCain's other "senior moments" like the 1993 division of Czechoslovakia and numerous campaign statements he can't remember and we're getting close to a clinical diagnosis.

There's also persistent talk of McCain taking a one-term pledge to avoid starting a second term at age 76. So here's a serious question: did McCain get an Alzheimer's test? At age 71, shouldn't he get one before he ends up like Ronald Reagan?
