His campaign was marred by typos, fundraising problems, an uproar that involved him questioning the bravery of the Colorado massacre victims and a murder-suicide carried out by a former friend.
When the voting was done, Bob Worsley, the wealthy founder of the in-flight shopping company SkyMall, was on top 56 percent to 44 percent, and journalists were being kicked out of Pearce's election night party in Mesa, Ariz.
"This is the same Russell Pearce who said he'd never lose a primary," political organizer Randy Parraz told the Arizona Republic on Tuesday. "He misjudged the fact that he was no longer a conservative Republican — he was an extreme tea party Republican. There's no comeback for Russell Pearce — he's done."
Parraz organized a successful recall of Pearce in November. At the time, Pearce was the state Senate president and arguably a more powerful politician than even Gov. Jan Brewer (R). But fueled by anger over some of Pearce's more outrageous actions, voters threw him out midway through his term in favor of moderate Republican Jerry Lewis.
This time around, Pearce hoped things would be different. Redrawn political districts meant he wouldn't have to face Lewis again. He also tried to rebrand himself as a nice guy to counter the reputation he gained as a flame-throwing immigration hawk after sponsoring the state's harsh immigration law known as SB 1070. His campaign materials showed him smiling and holding a baby.
But the trouble came early when news broke in May that an Arizona man had shot and killed four people in a suburban house outside of Phoenix before killing himself. The man turned out to be JT Ready, a border vigilante and former confidant of Pearce. The two had a falling out years ago after Ready's white supremacist views became public, but it left Pearce in a position of having to answer questions about the relationship in the middle of his campaign.
"When we first met JT he was fresh out of the Marine Corp and seemed like a decent person," Pearce said at the time, adding that the two eventually parted ways. "He was angry with me and stayed angry with me, and it has been several years since I have had reason to speak with JT."
The following month, Pearce ran into a series of financial problems. Records showed he was only able to raise $2,800 in the first five months of the year, way down compared to his haul of $260,000 to fight off the recall last year. He also hit another wall when word leaked that he was planning to host a fundraiser at a Mexican restaurant. Protesters upset with his stance on immigration ended up convincing two different restaurants to cancel the event.
In July, his nice-guy rebranding try took its biggest hit when he took to Facebook to let the world know what he thought about the Aurora, Colo., movie theater massacre where 12 people were killed and another 58 wounded. Pearce said it could have been stopped.
"All that was needed was one Courages/Brave (sic) man prepared mentally or otherwise to stop this it could have been done," he wrote. Days later, after it turned out that one of the victims had grown up not far from Pearce's district, he apologized.
The final humiliation, though, came just days later when campaign signs for Pearce went up all around his district bragging of an honor he received from a conservative education group. "Golden Apple Award for Eduction," the signs said, misspelling the word education.
On Tuesday, Pearce was in hiding following his defeat. Journalists on the ground in Arizona reported that his cell phone went straight to voicemail and photographers were being thrown out of his campaign party.
