Nobody has had their right to vote stripped from them.
Hmmmm ... they said the same thing about all those residents in the several majority-Black counties of Florida who claimed they had been disenfranchised during the 2000 election after their votes were thrown in the trash for undisclosed (and unproven) irregularities caused through no fault of their own (malfunctioning voting machines).
I'm not sure what having the "right" to vote is good for if your vote will not actually be counted as something meaningful. But ... after our history ... I guess we should just be glad we can go to the polls without being shot dead for it.
And the people of California should just accept the fact that having an opinion is one thing ... but having that opinion respected (by people who actually asked for it, no less!!) is definitely another.
