Site selection for the 1976 Worldcon was conducted by Discon II, the 1974 Worldcon. The bidders were KC in '76, Columbus in 1976, New Orleans in '76 and Highmore in '76 (the latter being a hoax bid which was not on the ballot). There was also a 34th World SF Convention Bidding Committee to hold it in Scandinavia, but it never filed.
|Bidder||1st Ballot||2nd Ballot|
|KC in '76||226||92||318||424|
|New Orleans in '76||117||78||195||253|
|Columbus in 1976||43||89||132||eliminated|
There also were a substantial number of "other" votes including write-ins for Highmore in '76 which were not included in the final report. Presumably they were also eliminated and redistributed and account for the total number of ballots increasing between the first and second round.
