From Rob Walch, creator and host of Podcast 411, and VP of Podcaster Development at Wizzard Media:

“Usher has made a music Video. He is allowing podcasters to include it as an item in their feed.  This is a get out the vote message, and the version below has an intro from Senator Obama.   You can also put the video player on your site. Usher has been very active in the get out the vote message.”

The link to the video is here, the enclosure tag (for your RSS feed) is here, and the video embed code for the single player version is here.

No word yet as to whether McCain supporter and reggaeton superstar Daddy Yankee is making a podcast-friendly video to help get out the vote.
