Alaska Gov. Sarah Palin launched a political action committee Tuesday to help support candidates for federal and state office. The committee, SarahPac, is dedicated to supporting "fresh ideas and candidates who share our vision for reform and innovation," according to its Web site. Palin catapulted to fame last year as Republican presidential candidate John McCain's running mate and is widely believed to be eyeing a presidential bid in 2012. Aides said the PAC will help serve as a vehicle for her political activities going forward. According to the Web site, SarahPac welcomes supporters of any political persuasion and will contribute to candidates of any party who share her ideas and goals. But Palin makes special note of the Republican Party on the site, saying it is at "the threshold of an historic renaissance" that should focus on health care, education and government reform.
