But luckily, all their activity convinces me that the proposition will really work. The soda industry has spent FIFTEEN DOLLARS per SF voter on this. [1] This tells me that it's not just about San Francisco. They are scared that if it works here, others will soon follow suit, reducing their profits. So it seems they believe that this sort of tax will have a substantial impact on soda consumption. They're telling me that voting for E means a chance of improving the entire country's health. So I'm definitely in.
