Proposition Ads (95)

I think one of the most confusion-causing elements of the election are the ads describing the various propositions on the ballot. While they are supposed to be informative, they often instead just seem to contradict each other. I am sure that those who create these commercials sincerely believe in their opinions (either in favor of or against the specific proposition). But I wonder if they intentionally lie to sway others.
Prop 8's ads are a good example of misinformation. As a former k-12 teacher, I know what the California curriculum actually is. So when I see those in favor of Prop 8 claiming that gay marriage will have to be taught in school, I know that this is incorrect. However, there are other propositions that I do not have first-hand knowledge of. How do I decide in those cases who to believe?
The ads surrounding Prop 2 are one example. Prop 2 is intended to mandate that animals that raised for food be allowed a quality of life. Those in favor of the proposition favor allowing animals to live in safe conditions and be able to walk around. As a vegetarian, I firmly believe in animal rights. Prop 2 sounds like it should be a great thing.
But then I see the ads against Prop 2. They state that we will have to import eggs from Mexico and that cases of salmonella will increase. Food prices will soar and many California farmers will go out of business. I don't want our neighborhood farmers to go bankrupt and I do want our food to be safe.
Those in favor of Prop 2 answer these ads by claiming that salmonella cases actually increase due to the cramped conditions in which we currently keep our animals. The price increases are accurate, but they amount to approximately a penny per egg.
Who is correct here? Who is telling the truth? I know what I want: Quality living conditions for our animals, regardless of whether or not they are raised for food; safe food products; a stabilized economy for our farmers; food at a reasonable price.
Can someone just be honest and tell me how we make this happen?
