In California illegals can vote with just a UTILITY BILL.

"If this is your first time voting and you are registered by mail without giving your California driver’s license or state identification number or the last four digits of your social security number, then you may need to show photo identification (e. g. valid driver’s license or state ID) or a paycheck, utility bill, or government document that shows your name and address."

What does it take in California to register to vote?
Yep, a UTILITY BILL..
Now what are the odds that out of all these millions of illegals in California that NONE of them registered to vote?
ZERO.
It will take another lawsuit and Supreme Court decision just to get this information.
What are they hiding?
LOTS of illegals voting!
