Billy Shaheen, the co-chair of Senator Clinton’s New Hampshire campaign, told a reporter yesterday that the GOP might use Senator Obama’s past drug use as an attack point.

Obama’s camp swifty issued a written statement, blasting the Clinton campaign of dredging up old issues, once again, to distract from her dismal poll numbers.

Team Clinton denounced the remarks, Shaheen himself apologized. Hillary Clinton apologized to Obama himself on the tarmac in Washington prior to their (separate) flights to Des Moines. But the story is not over.

Axelrod said the Muslim emails “may have come up” in the discussion, but Axelrod did not hear the conversation.
