Todd Akin is adding some celebrity star power to his campaign for U.S. Senate. Michelle and Jim Bob Duggar, stars of TLC’s “19 Kids and Counting” endorsed Akin last week. The conservative Christian family from Arkansas begin a series of campaign appearances tomorrow — with their 19 children — starting in Osage Beach. They’ll be at the Main Street Music Hall at 5 p.m. Akin will not be attending. He’s making other campaign appearances and preparing for his final debate with incumbent Senator Claire McCaskill, scheduled for Thursday.
