In one of the most heavily contested races today, Tea Party favorite Sharron Angle surpassed more than a dozen GOP candidates to become the Republican nominee who will face off against Senate Majority Leader Harry Reid in November.
Republicans in Nevada battled fiercely for a big prize: the chance to take on the Senate seat that Reid has occupied for more than two decades, and possibly render him the second Democratic party leader to be ousted by the Republicans in six years, after Tom Daschle in 2004.
Angle, a former assemblywoman, was in a neck-and-neck race with former state GOP chair Sue Lowden, who was favored by the state's Republican establishment.
What started off as a shoe-string campaign for Angle morphed into a million-dollar push to derail Lowden: The so-called Tea Party Express funneled half a million dollars into Angle's campaign, with hundreds of thousands more coming from other national conservative groups such as the Club for Growth.
Angle is an anti-tax crusader and an uncompromising conservative. She favors abolishing the Departments of Education and Energy, phasing out Social Security and Medicare, and removing the United States from the United Nations.
Reid's campaign views Angle's non-mainstream platform as one that can easily be targeted in the November midterm election.
Even though several incumbents have lost in primaries -- Nevada Gov. Jim Gibbons today became the first sitting governor to lose a reelection bid -- not all is lost for incumbents.
Longtime Arkansas Sen. Blanche Lincoln narrowly avoided becoming another casualty of anti-Washington sentiment, barely defeating Lt. Gov. Bill Halter, a favorite of labor unions and environmental groups in a close runoff race today.
Lincoln had slightly more than 50 percent of the votes, with Halter trailing closely behind, according to the Associated Press.
Lincoln's win is a major blow to labor unions and liberal groups, who poured millions of dollars into Halter's campaign, and in a state that normally doesn't garner this much national attention.
"The vote of this senator is not for sale and neither is the vote of the people of Arkansas," Lincoln said in her victory speech, rebuking national labor groups.
Lincoln, who won the support of both President Obama and former President Bill Clinton, was blasted by national labor unions for voting for the federal bank bailout and opposing the option of a government-run insurance plan in the health care bill and the Employee Free Choice Act, or card check, a high priority for the labor movement.
The groups wanted to paint Lincoln as an example of what would happen to Democrats who crossed liberal groups.
Lincoln's win is also a victory for Obama and Clinton, who campaigned for her in the final days of the race.
Lincoln has been in the Senate since 1998, when, at 38, she became the youngest woman to be elected. She serves as chair of several important committees, including Agriculture, Nutrition and Forestry, and the subcommittee on Energy, Natural Resources and Infrastructure.
Lincoln will face an even fiercer fight in November as Republicans take aim at her Senate record and take advantage of the anti-incumbent sentiment that has ended careers of Sen. Arlen Specter, D-Pennsylvania, and Sen. Bob Bennett, R-Utah.
