(AP) - It's been a busy first 100 days for PresidentBarack Obama. He's been tackling a steep recession, health care andglobal warming and trying to revamp America's image around theworld. The president is marking the day by flying to St. Louis toanswer questions at a town meeting. And he's holding a prime-timenews conference tonight back in Washington. It's the third of hispresidency. An AP-GfK poll gives the president a public approval rating of64 percent. The poll also suggests that for the first time inyears, more Americans think the nation's headed in the "rightdirection" than in the wrong one. This, despite a deepeningrecession that's thrown millions out of work. But Republicans are giving Obama a poor grade. They complainthat he hasn't kept his promise of bipartisanship -- that they'vebeen rebuffed in their efforts to offer solutions to the nation'sproblems.
