SNIPPET: "The Tea Party Express's endorsement of Rep. Walt Minnick (D-Idaho) has had little real political impact so far. After the endorsement, TPE's Sal Russo couldn't tell when we might see, say, a TV ad or mailer for Minnick -- although Mark Williams claimed that the group had planned to run ads supportive of Rep. Bart Stupak (D-Mich.) until he decided to support the final version of health-care reform. So what impact have we seen? A vast and efficient cheesing-off of tea party groups in Idaho."
