Note that I do believe rational thought and a belief in science and facts are qualifications to be vice president of my country. I'm crazy that way.
Also, I do think the question should be read as "qualified to be vice-president *to* John McCain," since that's really the question we're faced with. Because the odds that that man will survive *and* maintain his mental faculties through the course of a single presidential term seem to be going down by the minute.
