I agree with Keith Gurnees assertion that Proposition 32 is a measure that should be judged based on those who oppose it (Letters, Oct. 7.) In general, those groups are public employee unions. But I find it more informative to look at who is in favor of Proposition 32. The billionaire Koch brothers from Kansas, of all places, have donated $4 million to a Super PAC supporting Proposition 32. You be the judge.
