LOS ANGELES -- California voters will take to the polls Tuesday in the state's primary election, deciding nominees in several key races.

Polls open at 7 a.m. and close at 8 p.m. local time.

Meg Whitman and Steve Poizner have been making last-minute appeals for votes in the battle for the Republican gubernatorial nomination.

Whitman, the billionaire former eBay CEO, leads Poizner by around a 2-1 margin, according to recent polls. She was also an adviser and surrogate for Sen. John McCain's 2008 presidential bid.

Whitman campaigned in Woodland Hills Monday while Poizner, California's insurance commissioner and a self-made multimillionaire, attended a rally at the Green Hotel in Pasadena.

The Republican winner is expected to face off in the general election against state Attorney General Jerry Brown, a former two-term governor and the presumptive Democratic nominee.

The winner in November will succeed Republican Gov. Arnold Schwarzenegger, who can't seek re-election because of term limits.

Republicans running for U.S. Senate were also busy with last-minute campaigning. Carly Fiorina was in San Luis Obispo and Montecito Sunday while former Rep. Tom Campbell worked the phones from his home.

GOP State Assemblyman Chuck DeVore, a conservative who is a favorite of Tea Party activists, is also running for the senate seat.

The winner will face three-term Democratic Sen. Barbara Boxer in November, who is expected to face a tough re-election battle.
