With the clock ticking down Wednesday on the debt limit negotiations in Washington, presidential candidate Michele Bachmann announced her entertainment lineup for the Aug. 13 GOP straw poll in Ames, Iowa. The Minnesota Republican's campaign team released a program that includes country music singers Richie McDonald and Tim Rushlow, along with Christian artist Charles Billingsley. The announcement came at the end of a tense day in Washington for House Republicans, who remain divided over a plan by House Speaker John Boehner to raise the debt limit in exchange for sweeping spending cuts. Bachmann has not participated in any House votes so far this week. But her office said she plans to take part in votes scheduled for Wednesday evening. Bachmann, one of three House members in the GOP nominating contest, has drawn fire for missing a large number of votes over the past week of her campaign.
