Apparently, mistakes are made when those most affected by a proposed new law don't get any input on it. The Spokesman-Review describes how this happened with the new soda tax.
(By the way, it's a little thing, but here on the West Coast we call carbonated beverages "pop," not "soda." I know the AP Style Manual says "soda" since that's the term used nationally so it's not the Spokesman's fault, but we're just noting how grating it is to hear "soda.")
