I voted other. I did so because it is plain to me that the anti smoking crusade has led to hyperbolic claims about the effects of secondhand smoke. While I think it is very likely there is some effect, it is difficult to wade through what passes for analysis of the studies. The crusaders have ruined their credibility. As a consequence, I am having difficulty determining whether the danger posed is comparable to having your children live in a polluted city or ... what, exactly. And, no, I don't think that ANY amount of danger warrants a law.
For the record, I quit smoking (again) 2 years ago. I quit because I didn't like the effect on my body and mood day to day. I sincerely hope it was the last time I quit.
