Rationality of Voting, revisited

Today is election day in Clayton, NC. But hardly anyone is voting, and the N&O predicts that only a few hundred will vote today in a revote for the town council. Considering that Clayton is growing very quickly, and whoever sits on the council gets to make zoning and other growth-related decisions, any single voter could have a significant effect on their own future. If I was a developer, I would certainly spend 10 minutes of my time trying to guarantee a pro-growth councilperson, in order to earn thousands more in profits. In this case, voting might just be rational.
