A Federal lawsuit alleging widespread confusion over California's presidential primary rules asks that voter registration be extended past Monday's deadline until the day of the state's primary election on June 7.
"Mistakes are being made," said William Simpich, an Oakland civil rights attorney who filed the lawsuit Friday.
At issue is whether voters understand the rules for the presidential primary, which differ from those governing other elections in California.
Unlike statewide primaries — where voters now choose any candidate, no matter the political party — the presidential contests are controlled by the parties themselves. Democrats have opened up their primary between Hillary Clinton and Vermont Sen.Bernie Sanders to voters that have no political affiliation, known in California as having "no party preference."
