What to watch at the DNC Wednesday

Some things to watch for at the Democratic National Convention on Tuesday:

1. THE CLINTON SHOW: The former president, no stranger to talking at length at Democratic conventions, takes the podium. How much of it will be about Barack Obama - and how much about Bill Clinton?

2. ELIZABETH WARREN: It's a personal mission for the Democratic Party to get the late Sen. Edward Kennedy's seat back from the Republicans. Candidate Warren's opponent, Republican Scott Brown, didn't speak at his convention last week. But Warren is a star at the Democrats' and the featured challenger in arguably the most competitive Senate race this year.

3. THE WEATHER: Obama's outdoor stadium speech was moved indoors, where 50,000 ticketed will attempt to get into a much smaller venue.

4. OBAMA - GOOD FOR BUSINESS: That's what some CEOs on tap to speak are undoubtedly going to trumpet. But what will they have to say about Mitt Romney?

5. CHARLOTTE IS HOPPING: It's a totally different feel from last week in Tampa. Streets are packed, in part because there are more delegates, in part because of a smaller security perimeter and the convention hall's proximity to the city and restaurants.
