I think I've linked to his site before, but The Votemaster is wicked smart my friends.  And not in a boring, I'll admit, Al Gorish sort of a way.  Case in point, he always has little nuggets like this:

The AP had a story earlier this week that Pet owners prefer McCain to Obama. Now pollster.com has looked at the crosstabs on that poll carefully and demolished the idea. It turns out pet owners tend to be older married white people--and they favor McCain. Minorities and voters under 30 have fewer pets--and they favor Obama. In other words, the demographics of the petted and the petless are different. If somebody ran a poll on who false teeth wearers prefer it would probably be McCain, not due to his excellent plans for dental health insurance, but due to those people belonging to a distinct demographic group (old people). When analyzing polling data you have to be very careful not to confuse correlation with causation, a subject statisticians have been wrestling with for 50 years.

False teeth wearers for McCain!  Now THERE is a t-shirt just waiting to sold on CafePress, right?
