I've been concerned about McCain's "mis-steps" for quite some time. I remember Reagan making such errors, and then a few years after he was out of office it was announced he had Alzheimers. At mcCain's age, it is a distinct possibility. There is no question he gets the facts mixed up from time to time, as we've seen, its been recorded on video. I shudder to think if he was elected to the presidency, and he had such lapses in the middle of negotiations, or in meetings with foreign dignitaries. I am not comfortable taking such a chance.
