(1) In my comparison of IQ with party identification, I discovered a major change in the 2004 sample: people with high IQs have left the Republican Party and joined the Democratic Party.
(2) In my comparison of IQ with religion, I discovered that people with high IQs are less religious. Most people agree that the Republican Party has been more actively promoting a religious agenda. This would cause some high IQ secular Republicans to leave the party and encourage some high IQ independents to become Democratic.
(3) There is a significant correlation between IQ and region. The Northeast and Pacific regions have the highest IQ and the South has the lowest IQ. In the election of 2004, Bush's strongest support came from the low IQ regions and Kerry's support came from the high IQ regions. This electoral pattern is huge change from the pattern of the 1970s in which Democrats controlled the low IQ southern region. This regional shift is consistent with the conclusion that the Republican Party is losing support with high IQ voters.
We are observing a significant change in voting patterns. The Republican Party is gaining votes by attracting religious voters, but at a significant cost: the loss of high IQ and high socioeconomic status voters who were Republican because of their support for libertarian economic policies. These voters have tradtionally been the core of the Republican Party.
How will this change the policies of both parties?
