Margins of victory are generally higher in states with low voter turnout than in states with high voter turnout. A public choice economist who views voter turnout as determined by the costs and benefits of voting would most likely explain this phenomenon by arguing that, compared to people in states with little uncertainty about who is going to win, people in states with close races: Are less well informed Are less likely to be partisan Care more about who wins the election Consider their votes more likely to affect the outcome of the race
