Right they claim a large number of signers were not eligible voters, however they claim that none of these people voted.

It is pretty normal in California for signatures to be thrown out, though. They generally oversubscribe for that reason. However, it is expensive to get these signatures. I'm not sure exactly what went wrong in this case.

When money really wants something on the ballot -- like those competing Indian Casino proposals recently -- it gets there. Both those proposals got on the ballot. And then they spent the intervening time trying to shit on the other one.
