Given the high stakes, it's no surprise that a U.S. Senate primary in Kansas would use out-of-state resources to create its TV ads. But it was pretty dumb of the Senate campaign of Rep. Todd Tiahrt, R-Goddard, to include a shot of New York tax forms in a statewide TV commercial out this week — an attack ad targeting the "disturbing truth" about the "tax record" of rival Rep. Jerry Moran, R-Hays. TiVo and similar technology make every frame of everything on television subject to scrutiny and, in the case of the Tiahrt ad, national ridicule. By the way, the difference between Tiahrt and Moran on taxes is small; the American Conservative Union gave Tiahrt and Moran lifetime ratings, respectively, of more than 95 percent and nearly 92 percent. The U.S. Chamber of Commerce scores Tiahrt a 94 and Moran a 91.
