The Curtin Rises on the Democratic National Convention

Barack Obama's campaign began with the promise of change from business as usual in Washington. Then came the primaries; now comes the selection of veteran Delaware Senator Joseph Biden. Today, Obama has four days to reverse the slide, which now has him virtually tied with John McCain in what's supposed to be a Democratic year. This week's convention could be a lot more important than anybody expected. The delegates are still getting used to Obama's vice presidential choice, and it's not certain how many Hillary Clinton supporters are on board. Why Denver? What's the "western states strategy?" How about the pressure on tonight's main speaker, Michelle Obama?
