This time, the Kansas Chamber of Commerce and Americans for Prosperity-Kansas failed to purge state lawmakers who wouldn't toe their line. The groups targeted about half a dozen lawmakers who didn't support attempts to repeal the state's renewable energy standards. All of the lawmakers won their primaries Tuesday. "I was No. 1 on their hit list," Rep. Russ Jennings, R-Lakin, told the Kansas Health Institute News Service. "But I stood my ground for the people of my district, and they got it." In the 2012 primaries, the Koch-backed groups were successful in defeating several GOP moderates. Jennings thinks voters may have "some buyers' remorse about what happened two years ago."
