This is ugly. Billy Shaheen, co-chair of Hillary Clinton's New Hampshire campaign has gone after Barack Obama over his past drug use, arguing that the Senator's past could haunt him on the campaign trail:

"The Republicans are not going to give up without a fight ... and one of the things they're certainly going to jump on is his drug use," said Shaheen, the husband of former N.H. governor Jeanne Shaheen, who is planning to run for the Senate next year. Billy Shaheen contrasted Obama's openness about his past drug use -- which Obama mentioned again at a recent campaign appearance in New Hampshire -- with the approach taken by George W. Bush in 1999 and 2000, when he ruled out questions about his behavior when he was "young and irresponsible."

Shaheen said Obama's candor on the subject would "open the door" to further questions. "It'll be, 'When was the last time? Did you ever give drugs to anyone? Did you sell them to anyone?'" Shaheen said. "There are so many openings for Republican dirty tricks. It's hard to overcome." [Washington Post]

Talk about a self-fulfilling prophecy. If you're so concerned about people attacking Obama over his past drug use, you could start by not attacking Obama over his past drug use. The whole thing smacks of desperation as Obama rises in the polls.

Let's be real here. The last two presidents overcame allegations of drug use and found themselves in the White House. The only difference is that Obama has been particularly candid, and it really shouldn't even be necessary to point out that voters actually like honesty. He's told the truth when others lied. Explain to me how that will hurt him if others got away with using drugs and lying about it.

From where I sit, the only person who should be embarrassed by any of this is Hillary Clinton, whose campaign has apparently resorted to the same pathetic smear tactics used on her husband 15 years ago. Give us a break.

Update: Via DrugWarRant, the Clinton Campaign has wisely distanced itself from Shaheen's remarks, and he has even apologized for making them:

Clinton spokesman, Phil Singer, said, "These comments were not authorized or condoned by the campaign in any way."

....In a statement later, Mr. Shaheen said, "I deeply regret the comments I made today, and they were not authorized by the campaign in any way."
