A current survey predicts that in 20 years, 25% of the population will claim to be disinterested in any religion. Here are predictions about the consequences for party competition:
1. Secular voters will become an increasingly important component of the Democratic base.
2. American politics will become more polarized.
3. Republicans will have to choose between becoming a more overtly religious party and reaching out more seriously to the growing secular middle.
4. If secular voters become more aggressively antireligious, the Democrats' newfound faithiness faces big challenges.
