Jon Stewart and Steven Colbert are hosting the Rally To Insanity in Washington. Comedy Central is broadcasting it live on their website. You can watch it here.
Update: The live coverage of the Rally has ended on the Comedy Central site. There will be clips from the rally featured soon.
I am not sure if the Rally to Insanity will change anything, but it is a good try to raise awareness on what's going wrong in an entertaining way. Now Yusuf and Ozzy play at the same time. Pretty insane. I love the Daily Show. It is the only way to watch the news.
See also the Rally to Insanity site. It looks like there are really a lot of people there.
This is turning into a great show and music concert. Now Kid Rock is performing a brand-new song with Cheryl Crow.
