Heh... our state's initiative process has a judicial committee whose sole purpose is to rewrite misleading propositions and get rid of double negatives, etc. It can also deny "omnibus" initiatives (that should be split up, like e.g. "legalize weed, stop abortion" would get zapped).
It doesn't stop stupidity from reaching the ballot, but it does make it pretty clear when its a stupid initiative.
@Simonsy - its a mistake to look at a map and go by "Square mileage" - the results are by population density. Try to see if you can find a map that redefines a county's graphic size by population density. They have them for the U.S. but not sure about individual states.
