2012 Presidential Nomination Contest Turnout Rates

Last updated: 9/06/2012

VEP Total Ballots Counted turnout rate is the Total Ballots Counted divided by the voting-eligible population or VEP. In instances where the two political parties did not simultaneously hold their nomination contests, the first instance reflects turnout of the first party to hold their contest and the second instance reflects the total turnout of the two parties' contests combined, and the reported turnout rate is for this sum of the two contests.

2012 Primary Elections


Many states did not hold a Democratic nominating contest if only one candidate (i.e., Obama) qualified for the ballot. (a) The South Carolina Democratic Party held reorganization meetings starting on Feb. 28. (b) The Feb. 7 Missouri primary is non-binding. The Missouri Republican Party chose convention delegates in a March 17 caucus.

The denominator data reflect the April 1, 2010 Census and July 1, 2010 voting-age population estimates extrapolated to 1st of the month of a 2012 nomination contest, non-citizen estimates from the 2010 American Community Survey (I have not extrapolated citizenship statistics since the 2009 ACS is not comparable as it is weighted to the 2000 census), the year-end 2010 DOJ prison report and the year-end 2010 DOJ probation and parole report.
