President Obama's campaign is previewing tonight's convention speech with a video entitled "Promises Kept."

"From cutting taxes for middle-class families to bringing about comprehensive health care reform to re-investing in education and infrastructure, President Obama has kept his promise to rebuild America for millions of families," said the Obama campaign in an e-mail including the video.
