OK, there was former Sen. Bob Dole pitching Viagra years ago. But he was already out of office when he became a spokesman for the virility drug. Now comes long-shot candidate J.D. Winteregg, a Tea Party-oriented primary challenger to Speaker John Boehner, R-Ohio, who’s running a Web ad inspired by those unavoidable erectile dysfunction ads that have created awkward moments for millions of parents watching TV with their children. A high school and college French teacher, Winteregg doesn’t have much to lose with such an unconventional approach. He’s raised very little money and has very low name recognition. Winteregg’s ad spoofs Cialis spots specifically. It also plays off the mischievous mispronunciation of Boehner’s name — well known to anyone who’s read the comments sections of blog posts about the speaker.
