California billionaireTom Steyer has spent more than $18 million so far in his bid to convince Arizonans to support a constitutional mandate that half of all electricity come from renewable sources by 2030.

It seems a bit out of Alice in Wonderland. But if you support the goals of those who put Proposition 305 on the ballot -- opposition to expansion of vouchers -- you have to vote "no'' in November.

A measure Republican lawmakers put on the November ballot could determine how much Arizonans actually know about who is trying to influence political campaigns.
