As the recall election of Gov. Scott Walker (R-WI) nears, a media group is arguing that certain Wisconsin radio stations devote a disproportionate amount of air time to Walker’s fans, while effectively silencing supporters of Tom Barett, his opponent. The Media Action Center released a letter today saying that Wisconsin Recall radio coverage was extremely tilted toward Walker on two different stations — WTMJ and WISN, which is owned by the right-leaning media company Clear Channel. In one day alone, the group found that anti-Barret, pro-Walker rhetoric took up 49 minutes, while the reverse had only two minutes of airtime. The numbers were equally drastic for pro-Democratic verus anti-Democratic coverage. The Media Action Center sent their letter to the FCC, arguing that the stations are violating the Zapple Doctrine, which says stations must give equal amounts of free promotion to every candidate in the 60 days leading up to the election.
