Does air conditioning make people vote Republican?

Salon reports:

Do a little more math, and you'll see that before air conditioning redistributed the country's population, the Florida recount wouldn't even have been necessary. In the 1940s -- the last decade before the air conditioner became a must-have home appliance -- Al Gore's states contained a decisive 291 electoral votes. As Hofstra professor James Wiley pointed out back in 2004, air conditioning "induced a major population shift within the country that eventually led to the Electoral College defeats of the Democratic presidential candidates in 2000 and 2004."

Democrats say the most amazing things sometimes.
