Gateway Streets has some awesome Prop A maps uploaded on Flickr. This one shows the percentage increase in the yes vote compared to the 2008 election by township:
As you can see when comparing this election (with the tea party as the primary opposition) and the last election (when the tea party did not yet exist in its current form), every single county increased it's support for the sales tax! The tea party considered this across the board loss "not too bad," and claimed that John Burns did a "remarkable" job.
Let's hope they continue to run "remarkable," "not too bad" campaigns for a long time to come!
