Anti-Harassment Tools/SecurePoll Improvements/Test Results/20 4 5000 1685033555

Comments

SecurePoll eliminates all candidates. I assume this is because all the candidates have equal votes. In this case, I think we plan to defer to the election admins how to proceed.

This is possibly the same/similar to 20_6_5100_319413701, 20_6_5000_2048397232 and 5_3_100.
