The formula for estimating turnout for the joint primary elections is:

(A x B) + C + D = E

Where:

A = the percentage of voter turnout for the office that received the most votes in the most recent
comparable party primary election (percentage is the sum of all votes cast for the office that
received the most votes in the most recent comparable party primary election divided by
the number of registered voters).
B = the number of registered voters as of October preceding the primary.
C = 25% of the number resulting when you multiply A x B.
D = Other party's estimated turnout figure.
E = Preliminary Estimated Turnout for Joint-Primary Election.
