In Kalifornicate: the candidate or measure with the most votes wins even when there are enough votes that are verified as illegitimate thus proving a loss. And invariably, no one ever goes to jail for vote fraud in Kalifornicate. This e registration does one thing, it broadens the allowance for vote fraud to be legal and on a larger scale.
If you're against this, I'm not sure what exactly it is that you support -- banning all voter registration?
