Very interesting. More of a political statement since the Mayor won her election in a very contested and unique election process. If you have time read about how the Oakland Election for Mayor was achieved. She actually got more second place votes than 1st place but the person who received more 1st place votes did not achieve the required consensus so the votes of the second place candidate were then tallied which gave the current mayor the win.
At least that is how I understand it and was explained to me by an Oakland resident/activist.
