President Obama's Support Is Evaporating

Republicans presidential candidates dominated this weekend's political news while President Obamas approval ratings sank to their lowest point since he took office. Today it was his turn to visit Iowa, part of a three-state tour to shore up support from crucial constituencies. Obama has been denounced for filling the White House with Wall Street bankers and defended for doing the best he can with the bad hand he was dealt by George Bush and Republicans in Congress. But Independents are among those giving the President ratings so low he's vulnerable to the Republicans.
