A Baha'i may not vote in a primary election if in order to do so he or she must declare membership or affiliation with, or support for, a particular political party. But if the ballot is secret, a Baha'i is free to vote in any political election provided that he does not, by doing so, identify himself with any political party and bears in mind that he is voting on the merits of the individual rather than because he belongs to one party or another.
