State Rep. Raul Labrador walloped Republican establishment favorite Vaughn Ward in Idaho’s 1st District congressional primary. Idaho native Sarah Palin campaigned for Ward, who had worked in the McCain presidential campaign in 2008. Labrador drew strong support from Tea Party activists. According to Politico, “Ward’s defeat also came despite his high-profile support from former Alaska Gov. Sarah Palin, who did more to assist Ward than she did for almost any other House candidate. Last Friday, she headlined a rally and fundraiser for Ward, and her parents and in-laws were supporters of Ward’s campaign.”

Lots of Republican incumbents lost their legislative seats, too, suggesting the continuing power of Tea Party activism and general populist unrest.
