The debt-limit showdown isn't helping Americans' low opinion of their leaders. Just 7 percent of those surveyed by USA Today/Gallup Poll think both sides are negotiating in good faith. At least two-thirds say Republicans and Democrats in Congress are putting politics first. Fewer than half think there will be a deal in time for the Aug. 2 deadline. The overall approval ratings: President Obama, 45 percent; congressional Democrats, 33 percent; congressional Republicans, 28 percent.
