The BPC 2012 vote count is low because their document was written just after the 2012 election, before final counts were in. Their voting-eligible population (VEP) does not include adjustments for felons (see p.13). The United States Elections Project, by Michael McDonald calculates VEP including citizenship and adjustments for felons. The site's data on turnout as percentage of eligible voters (VEP), is slightly higher and similar to BPC: 2000 55.3%, 2004 60.7%, 2008 62.2%, 2012 58.6%. McDonald's voter turnout data for 2016 is 60.1% and 50% for 2018.
