There is a video contest at Moveon.org called "Obama in 30 Seconds"
http://www.obamain30seconds.com/. The basic rule is that the video is 26 seconds long and they add the tag at the end. I added my own for the YouTube version.
I've submitted some videos from some video/photographs from last year's Madison Obama table and a couple Obama speeches I videotaped. I do the VO and composed the music including Obama's "Fired up! Ready to go!". The message is about grassroots politics and that You are the Cavalry. This message goes out to any and all people supporting their candidate.
The deadline to submit to the contest is April 15. I have more I'm going to submit, but figured I'd share these... If you're interested in sending in a video or two, it's not too late!
