For every person who claims he’ll vote for Obama then secretly votes for McCain, I’m sure there’s also a person who publicly claims to support McCain who will really vote for Obama. Right? I mean, isn’t this idea of people who make public statements then secretly do the opposite something that happens all the time, in all directions, for all kinds of different reasons? And doesn’t the fact that it does happen in both directions tend to dampen any statistical significance?
You know there are people who don’t want to publicly reveal they have changed their mind about McCain and will vote for Obama.
