Using MongoDB 2.7.8 I used mlaunch to start a replica set with 50 nodes. From the logs I can see that 33 nodes cast a vote in the election, even if only 7 nodes have votes=1. Note that according to the manual (http://docs.mongodb.org/manual/reference/replica-configuration/#local.system.replset.members[n].votes) it should in any case not be possible to have more than 7 nodes voting in an election.
