It wasn't pretty when Bill Shaheen, co-chair of Hillary Clinton's campaign, suggested Barack Obama might be tarred as a drug dealer because Obama has written about his drug use as a young man. As Addie wrote, "Here, we find Shaheen, as Clinton's surrogate, not simply mining a rival's past for unflattering information, but deploying that information in a way that he likely knows will evoke a racial stereotype of the black drug-thug in the minds of voters who have never known actual black people."
So it's no surprise Shaheen is a goner. Here's his statement from the campaign press release:
I would like to reiterate that I deeply regret my comments yesterday and say again that they were in no way authorized by Senator Clinton or the Clinton campaign. Senator Clinton has been running a positive campaign focused on the issues that matter to America’s families. She is the best qualified to be the next President of the United States because she can lead starting on day one. I made a mistake and in light of what happened, I have made the personal decision that I will step down as the Co-Chair of the Hillary for President campaign. This election is too important and we must all get back to electing the best qualified candidate who has the record of making change happen in this country. That candidate is Hillary Clinton.
