Tuesday is the biggest primary day of this year's elections as voters in 11 states are going to the polls, and Tea Party candidates may have even more surprises in store.
The anti-Washington mood has already claimed two U.S. Senators this election year. Arkansas Senator Blanche Lincoln will be hard-pressed not to become the third in Tuesday's vote.
Polls show her in a dead heat with her liberal challenger Bill Halter in the Democratic primary runoff.
In the West, California features two marquee races with women from the business world.
Click play for an update with John Waage and preliminary results in Tuesday's primaries.
Former Hewlitt-Packard executive Carly Fiorina is favored in the Republican Senate primary against congressman Tom Campbell and conservative state Senator Chuck DeVore. The winner takes on three-term incumbent Barbara Boxer.
In the governor's race, former eBay executive Meg Whitman is bidding to become California's first women governor. She has spent nearly $80 million dollars trying to defeat Republican opponent Steve Poizner. If she wins, she'll face former Governor Jerry Brown in November.
"I feel good about where we are in the primary, and then, we've got to turn, and we've got to take on Jerry Brown and the unions," Whitman said.
In Nevada, there's a heated battle to try to replace Senate Majority Leader Harry Reid. Tea party favorite Sharron Angle has come from nowhere to take the lead in the polls against former Republican chair Sue Lowden and former University of Nevada Las Vegas basketball star Danny Tarkanian.
In South Carolina, state Representative Nikki Haley, another candidate backed by the tea party and Sarah Palin, jumped from fourth place to first this spring in the Republican primary race for governor.
Then came accusations from two men, one a blogger and another connected with one of her opponents, that they spent the night with her, a charge she has repeatedly denied.
"This is dirty politics. This is what people are tired about," Haley said.
In a state wearied by sex scandal stories of the current Governor Mark Sanford, Haley is supported by the governor's popular ex-wife Jenny Sanford.
Across the country, primary races for Congress are also expected to reflect voter fear and anger over government spending.
