The myth of the rational voter. Why democracy choose bad policies. Bryan Caplan.

The greatest obstacle to sound economic policy is not entrenched special interests or rampant lobbying, but the popular misconceptions, irrational beliefs, and personal biases held by ordinary voters. This is economist Bryan Caplan's sobering assessment in this provocative and eye-opening book. Caplan argues that voters continually elect politicians who either share their biases or else pretend to, resulting in bad policies winning again and again by popular demand.
