CNN polls are about as reliable as AOL polls (which had McCain winning all 57 states). CNN's website does not attract enough normal people to enable them to conduct a poll with any meaning. Non-moonbat types are generally elsewhere. This holds true as well for CNN's cable television audience.
The fact that McCain is doing as well as he is in this "poll" is sick and horrible news the CNN crowd. It means McCain is actually about 12 points ahead in a real poll.
