2012 Presidential Nomination Contest Turnout Rates

Last Updated: 9/06/12

Please see the FAQ for information on the construction of these statistics. The demoninator 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.

VEP Total Ballots Cast Turnout Rate is the total ballots cast 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 context and the second instance reflects the total turnout of the two parties' contests combined and a turnout rate is reported for the two contests.

Again, please see the FAQ for more information.

For comparison purposes, you may wish to consult statistics for the 2008 and 2004 presidential primaries.

Notes: Many states will not hold a Democratic nominating contest if only one candidate 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.
