hurricane katrina. isaac and tonight former president bill clinton making the speech for president obama. >> i nominate him to be the standard bearer of the democratic party. i like the argument for president obama's reelection a lot better. here it is. he inherited a damaged economy. he put a floor under the crash. he began a long, hard road to recover and laid a foundation for a modern economy that will produce millions of good new jobs, vibrant new businesses and lots of new wealth for innovateors. now... are we want to be today? no. and is the president satisfied? of course not. but are we better off than we were when he took office?
