A Confusing Proposition

November is election month, and in an attempt to be a good citizen, I am (slowly) making my way through all the propositions, and candidates so I can make informed voting decisions...only it's not working. (Part of the issue is I don't even understand what some of the propositions are about.) The problem with looking at issues and candidates for both sides is that when you actually figure out what they are arguing about they tell you exact opposite things about it! One side says it it will create jobs, the other side says it will destroy them. Both of those statements cant be true. And I realize one of them must be a lie, or at the very least less true but I'll be damned if I can figure out which side it is. For example:

Proposition 21: Established a $18 vehicle license fee that is supposed to go to State Parks and wildlife programs.

Prop 21 is designated for maintenance and upgrades of park facilities, upkeep of park lands and conservation efforts of state parks and sancutaries. It says that the money is specifically dedicated to parks and isn't supposed to be used for anything else. That sounds awesome doesn't it? And as a bonus, all the cars that pay the tax will get free entry into any state parks, for an unlimited number of visits! Even better right? So I was about to vote YES! but then I read the opposing argument.
The "Vote No" folks claim that the money won't really go to the parks, but be shifted into other areas to pay for Sacramento's busted budget. They claim the State Parks/ conservation allocation is just and attractive "shell" used by the politicians to get people to vote yes on it, and once the money starts coming in, they will immediately begin siphoning it off to other areas. They further claim that the parks will be in worse shape than they are now because if Prop 21 passes but the money gets routed elsewhere and visitors not longer have to pay an entrance fee the parks will be at a double loss.
So now what am I supposed to do? How do I even know who is telling the truth? Can the money be used on other things or not? Can voting No on a tax for state parks actually help them out more than voting Yes? Does that even make any sense? It's so frustrating! And I haven't even made it to the politicians yet! Ugggg. Does anyone else feel this exasperated around election time?
