The biggest battles for movement conservatives are looking decidedly tougher. Both FreedomWorks and Club for Growth remain committed to defeating Hatch in 2012, but are having trouble identifying a challenger who matches Chaffetz’s tea party credentials with a political background to boot. Chaffetz would have united conservative opposition against Hatch and, as a congressman, would have had a much stronger fundraising base than whoever takes his place.

“Bottom line, this was never about Jason," said FreedomWorks national political director Russ Walker. "It was always about Orrin Hatch. While Jason would have been a very good candidate... there's a lot of other people who have approached us. This race might become a little more dynamic now that he's out of it."

State Sen. Dan Liljenquist has received the most focus after Chaffetz, but he hasn't yet committed to running. Liljenquist has won support from conservatives for reforming the state pension system and tackling Medicaid. But some conservatives see parts of his record as problematic.

"I like Dan. I don't want to be throwing darts at him.... [Immigration] is just not a passionate issue for him, and he hasn't ever really been on that side, and so that is something that is concerning to a lot of the conservative people here in Utah," said Utah tea party organizer David Kirkham.

The dilemma between finding a candidate who’s ideologically pure and also has the ability to win statewide elections is proving to be harder than expected. Immediately after the 2010 midterms that saw tea party-aligned Paul LePage win the Maine governor's race, tea party activists identified Snowe as a promising target. Throughout her career, she’d always been inclined to compromise, a glaring red flag. Polls showed her support lagging among Republicans, and she seemed ripe for defeat in a primary where only the most committed Republicans show up.

But so far, the threat hasn’t materialized. Two little-known tea party activists have announced campaigns, but haven’t raised enough money or built an organization that poses a threat to her nomination. LePage has gotten behind Snowe’s reelection, giving her critical credibility. And she’s looking to be in solid position to win.

“I just don’t see nearly the amount of rancor during this primary season that we did last year,” said Chris LaCivita, a Virginia-based Republican consultant.

LaCivita has reason to feel that the anti-establishment forces have peaked. A former adviser to George Allen, he watched Jamie Radtke, the chairwoman of the Federation of Virginia Tea Party Patriots, enter the race. Her insurgent candidacy drew plenty of media attention and excitement from Democrats expecting her to play the role of Nevada’s Sharron Angle or Delaware’s Christine O’Donnell – who defeated establishment Republicans in the 2010 midterms but lost to Democrats in the general election.

But unlike Angle or O’Donnell, Radtke has struggled to raise much money and win attention from the conservative media, and is mired in single-digits in the polls. Allen has hardly addressed her on the campaign trail, and has already trained his focus on Democrat Tim Kaine.
