Atlanta ? Whipped up by conservative commentators and bloggers, tens of thousands of protesters staged “tea parties” around the country Wednesday to tap into the collective angst stirred up by a bad economy, government spending and bailouts.

The rallies were directed at President Barack Obama’s new administration on a symbolic day: the deadline to file income taxes. Protesters even threw what appeared to be a box of tea bags toward the White House, causing a brief lockdown at the compound.

Shouts rang out from Kentucky, which just passed tax increases on cigarettes and alcohol, to Salt Lake City, where many in the crowd booed Republican Gov. Jon Huntsman for accepting about $1.5 billion in stimulus money. Even in Alaska, where there is no statewide income tax or sales tax, hundreds of people held signs and chanted “No more spending.”

“Frankly, I’m mad as hell,” said businessman Doug Burnett at a rally at the Iowa Capitol, where many of the about 1,000 people wore red shirts declaring “revolution is brewing.” Burnett added: “This country has been on a spending spree for decades, a spending spree we can’t afford.”

In Boston, a few hundred protesters gathered on the Boston Common — a short distance from the original Tea Party — some dressed in Revolutionary garb and carrying signs that said “Barney Frank, Bernie Madoff: And the Difference Is?” and “D.C.: District of Communism.”

Texas Gov. Rick Perry fired up a tea party at Austin City Hall with his stance against the federal government, as some in his U.S. flag-waving audience shouted, “Secede!”

But unlike many events around the country, politicians were not allowed to speak at a separate rally in San Antonio.

“They are welcome to come and listen to us, for a change,” organizers said in a statement.

In Atlanta, thousands of people gathered outside the Capitol, where Fox News Channel conservative pundit Sean Hannity broadcast his show Wednesday night. One protester’s sign read: “Hey Obama you can keep the change.”

One of his guests was Samuel “Joe the Plumber” Wurzelbacher, who made news during the presidential campaign when he asked Barack Obama about taxes. The crowd cheered many of Hannity’s stances against higher taxes and moves by the Obama administration so far.

Julie Reeves, of Covington, brought her Chihuahua, Arnie, who wore a tiny anti-IRS T-shirt. “I want the government to get its hand the hell out of my wallet,” Reeves said.

The tea parties were promoted by FreedomWorks, a conservative nonprofit advocacy group based in Washington and led by former Republican House Majority Leader Dick Armey of Texas, who is now a lobbyist.

Organizers said the movement developed organically through online social networking sites such as Facebook and Twitter and through exposure on Fox News.
