moment. Thank you, cecilia vega. For more, we go to jake tapper in washington. Good morning, jake. Reporter: Good morning, lara, how are you? Good. I want to start with the incident with the two allegedly drunken delegates. Not the way the obama campaign would want to start this week. Is it a big deal? It's not. We think of conventions as ways for politicians and parties to present their case to the american people. For thousands of delegates, these are conventions like any other. That means a lot of men behaving badly. So you say present their case. What are the top three things you think need to happen this week for obama? First, he has to rally the base. Easier to do when you're a candidate than when you're an incumbent. He has to get the voters he fe needs to turn out excited for him. Young people, latinos, labor. He needs to make an economic case to the ambivalent obama voters at home. What will the next four years look like. Why would the economy be better the next four years than the past four years? And the last thing is make people feel proud about having voted for him in 2008. Even liberals say one of the most devastating lines of romney is what kind of presidency has the obama campaign had if the best feeling you had was the day you voted for him? On wednesday, bill clinton is the main speaker. At a time, there was bad blood between the two. Is that all behind them now? It's mostly behind them. There's some tension between presidents from the same party. Bill clinton and jimmy carter didn't get along. Obama needs clinton. He needs him to make the case. There's nothing a guy like clinton likes better than feeling needed. He'll be there wednesday. Front and center, the attention spot light on him. Thanks, jake. George and diane will lead the prime time coverage on the national convention, starting tomorrow night, 10:00 p.M. Eastern on abc.
