As a Kansan, I feel like I can provide a pretty good answer to this. It's because we believe in the principal of the thing. We believe that minimal government intervention in the economy will result in the best overall long-term outcomes.

And believe it or not, we do still have a low unemployment rate and high overall standard of living. Sure, Brownback made some pretty bad decisions about tax strategy. But the fact remains that low levels of government intervention have worked pretty well for us so far... especially for the lower class. Having lived in the NYC area for several years, I can tell you that lower-class citizens can maintain the same standard of living here with a 40-hour-per-week job that people in the city work 90 hours a week to maintain.

Voting for a set of principals that might not translate into money in your pocket the next day does not make you stupid or misinformed. It means that you're principled. It means that you're not acting like a five year old and voting for the politician that throws-out the best hard candies.
