Guide Note: A Hillary Clinton campaign ad debuted on March 3rd that included footage of Barack Obama in which the rival candidate's skin seemed to have been darkened. The change from the original footage was quickly caught by diarists at Daily Kos, and the story soon spread to mainstream news sources including FOX News. The Clinton campaign has made no comment as of 3PM EST, March 4th, and it remains unclear whether the darkening was intentional, or whether the entire commercial was released (or reproduced) in muted tones. Fast Facts:
