I'm pretty sure most don't have alcohol anymore because in the early 2000's or late 90's they all started putting "Does not contain alcohol" in big words on the front of their products. The hairsprays still contain some but not as much as before.
I don't know if CA is different because of the tougher environmental regulations out there, but almost any hairspray you pick up has alcohol, especially if it's an aerosol. If you read the ingredients, "Alcohol denat" or "SD Alcohol" will be one of the top ingredients (it's often the first ingredient). I have two different kinds of hairspray in my bathroom right now and they both list alcohol as the first ingredient. (No, I'm don't use them at once. One is almost gone so the second bottle is just a replacement.)
Ingredients on grooming products are listed in descending according to the percentage of their make up within the solution. In other words, the first ingredient is what they use the most of in the product, and the last ingredient is what they use the least of. (If you look at many products that claim to contain an uber-special ingredient, it's usually towards the very end of the list because they actually use very little of it.)
The only non-alcohol hairspray I can find out here is by Loreal, and it's pretty expensive (about $9), and doesn't work for my hair at all. It acts more like a spray gel. I prefer other kinds (and they're usually less than half that price.)
Gels and styling aids that don't contain alcohol are a little easier to find, but you really have to read the ingredients. Usually, if you're after mega-hold or something that will hold an extreme style, it's going to contain alcohol.
(I'm just mentioning all of this because the last year or so I've been trying to switch to alcohol-free products, but have found it impossible to do with certain things like hairspray.)
