 Whether the Demographic Argument succeeds or not depends on a few assumptions about voter and politician behavior. First, political scientists overwhelmingly find that voters do not vote their self-interest, but instead vote for what they perceive to be the national interest. (See the dozens of papers cited at Brennan and Hill 2014: 38–9n28.) Second, it might turn out that disadvantaged citizens are not informed enough to vote in ways that promote their interests—they might not have sufficient social scientific knowledge to know which candidates or political parties will help them (Delli Carpini and Keeter 1996; Caplan 2007; Somin 2013). Third, it may be that even in a compulsory voting regime, politicians can get away with ignoring the policy preferences of most voters (Gilens 2012; Bartels 2010).
