I know this is at best a more version of the old BC tradition of the hamburger race, but it is one of the few things out there I can actually measure in the local elections.
As of abotu 60 seconds ago the number of members of each facebook ground was:
Rob is still in that early phase Facebook groups have when lots of people join. He quickly has passed the other two, though his lead is not that strong.
The only other mayor candidate out there with a Facebook group is Sean McNulty in Central Saanich. He remains at 279 members.
The hamburger poll existed in BC for many years because polling was not allowed during elections. To get publicity and give the media some idea of public support, a restaurant in Vancouver sold hamburgers by the name of the politicians or parties.
