In case you missed it, the Idaho R’s fired the first major salvo in the U.S. Senate campaign a week ago by issuing a news release linking John Edwards’ infidelity to Demo Larry LaRocco’s distant past. As an, ahem, public service, the R’s wanted to alert newcomers to the old affair that helped the late Helen Chenoweth unseat LaRocco in 1994. “Idaho has changed a lot in 14 years, with a lot of new voters arriving in that time,” GOP Chairman Norm Semanko said in the release. “I wonder how well those new arrivals truly know Larry LaRocco and his past?” Immediately, state Demo chief Keith Roark fired back to remind the R’s about their own Sen. Larry Craig, with his wide stance and wandering feet, and other straying R’s. Then, LaRocco issued his own release to denounce the “tawdry shots” from both parties. So which side finished with the most mud on its face? Dennis Mansfield, a social conservative who ran unsuccessfully for Chenoweth’s seat, said his fellow R’s should be ashamed of themselves. In his blog, Mansfield admonished: “Larry LaRocco should be judged on his record and on his political beliefs this time around. He’s not John Edwards-lite, nor is his situation. In years since, he has shown himself a faithful man who loves his wife, his family and his state. He’s presented himself twice now for the citizens to consider as an elected official. Judge him on that. To quote Alice Cooper: ‘School’s out forever ...’ Let’s grow up.” Bingo. Oopsy
