McCain's memory problems

You really must read Frank Rich's opinion piece called The Candidate We Still Don’t Know. Here's the part that disturbs me most:

Most Americans still don’t know, as Marshall writes, that on the campaign trail “McCain frequently forgets key elements of policies, gets countries’ names wrong, forgets things he’s said only hours or days before and is frequently just confused.” Most Americans still don’t know it is precisely for this reason that the McCain campaign has now shut down the press’s previously unfettered access to the candidate on the Straight Talk Express.

Can you just imagine how dangerous it would be for this country to have someone that cognitively impaired in charge?
