Sarah Palin told thousands of tea party activists assembled in the dusty Nevada desert Saturday that Sen. Harry Reid will have to explain his votes when he comes back to his hometown to campaign.
The wind whipped U.S. flags behind the former Alaska governor as she stood on a makeshift stage, holding a microphone and her notes as she spoke to the cheering crowd. She told them Reid, fighting for re-election, is "gambling away our future."
"Someone needs to tell him, this is not a crapshoot," Palin said.
About 7,000 people streamed into tiny Searchlight, a former mining town 60 miles south of Las Vegas, bringing American flags, "Don't Tread on Me" signs and outspoken anger toward Reid, President Obama and the health care overhaul.
Palin told them the big-government, big-debt spending spree of the Senate majority leader, Mr. Obama and House Speaker Nancy Pelosi is over.
"You're fired!" Palin said.
A string of polls has shown Reid is vulnerable in politically moderate Nevada after pushing Mr. Obama's agenda in Congress. His standing has also been hurt by Nevada's double-digit unemployment and record foreclosure and bankruptcy rates.
The Searchlight native responded with sarcasm to the large crowd gathered in the hardscrabble town of about 1,000 he grew up in.
"I'm happy so many people came to see my hometown of Searchlight and spend their out-of-state money, especially in these tough economic times," Reid said Saturday in a statement released through his Senate campaign. "This election will be decided by Nevadans, not people from other states who parachuted in for one day to have a tea party."
Traffic on a highway leading into the town was backed up more than 2 miles Saturday afternoon as people gathered for the rally, which kicks off a 42-city bus tour that ends in Washington on April 15, tax day.
Cars and RVs filled the dusty area where the rally was held, as people set up lawn chairs and braced against the stiff wind whipping up dust clouds and blowing dozens of flags straight out.
The rally that's been called a conservative Woodstock takes place just days after the historic health care vote thatand divided Congress and the nation. The vote was followed by aimed at some Washington lawmakers, mostly Democrats who supported the new law.
Conservative columnist Andrew Breitbart disputed accounts that tea party activists in Washingtonamid the health care debate, although he didn't provide any evidence.
"I know you're not a racist group," he told the crowd.
Palin, the 2008 Republican vice presidential nominee, appeared after spending Friday and Saturday morning, the Arizona Republican who led the 2008 ticket.
Now a Fox News analyst and potential 2012 presidential candidate, Palin faced criticism afterover 20 Democratic districts. She also sent a tweet saying, "Don't Retreat, Instead - RELOAD!"
She said Saturday she wasn't inciting violence, just trying to inspire people to get involved.
"We're not going to sit down and shut up. Thank you for standing up," Palin said.
"So far it's nice and peaceful," Rivera said.

The tea party movement is a far-flung coalition of conservative groups angered by Washington spending, rising taxes and the growth and reach of government. It takes its name from the Boston Tea Party in 1773, when colonists dumped tea off English ships to protest what they considered unfair taxation by the British crown.
"Some of you are registered Republicans. Some of you are ... what we used to call Reagan Democrats," Palin said. "And some of you are like so many of my friends and my family, including my own husband, just independent, not registered in any party. Just true, blue-blooded Americans."
Some people milling around at the rally wore old-fashioned costumes and carried drums, lending to a festival-like atmosphere. Organizers had said up to 10,000 people might come; around 1 p.m. local time, police estimated the crowd was about 7,000.
Leonard Grimes, a 70-year-old retired logger, said the nation is drifting toward socialism, and he's not convinced Mr. Obama is eligible to be president.
"I'd like him to prove he's an American citizen," said Grimes, a registered independent who is originally from Michigan but now lives in Golden Valley, Ariz.
He called the health care bill "a joke, just another way to enslave the American public."

Ketha Verzani, 60, said she came to the rally from her home in Las Vegas "to stand with those who want to clean house."
The Republican opposes the health care bill and worries Americans are losing their rights, including parental rights and gun rights.
"It seems like every day more and more of our rights are being taken away," Verzani said, sporting a Palin 2012 button to show support for the former Alaska governor who "doesn't beat around the bush."
Reid supporters set up a hospitality tent Saturday in the parking lot of a Searchlight casino, about a mile from the tea party rally. The Senate leader planned to spend part of the day at a new shooting range in Las Vegas with National Rifle Association Executive Vice President Wayne LaPierre.
Luis Salvador, 55, an unemployed fire sprinkler fitter, drove down from Las Vegas to support Reid, who he said has done a lot for the state and doesn't deserve the protest brought to his hometown.
"You don't come to a man's house and start creating a ruckus," said Salvador, a registered independent. He and several others taped signs saying "Nevada Needs Harry Reid" to the side of a truck near the highway that runs through town.
Another Reid supporter, Judy Hill, 62, said she doesn't understand the hatred of Reid. The longtime Democrat from Searchlight, a town of about 1,000, said she thinks people just don't know the man she calls a friend.
"They listen to the rhetoric. I think he's very misunderstood and under-appreciated," she said.
