Keeping the Kennedy mystique alive.

After a candid speech discussing his substance-abuse problems, Rep. Patrick Kennedy sauntered into a DC watering hole and ordered up so many vodka shots that the bartender refused to serve him any more, it was reported yesterday.

Kennedy, the troubled son of the late Sen. Ted Kennedy, downed at least six shots of straight-up vodka before the bartender cut him off, a source told the Roll Call's Heard on the Hill blog.

He strolled into the Capitol Lounge just hours after being recognized for helping people with mental-health issues.

When a patron offered to buy him a drink, Kennedy eagerly ordered up a vodka shot, according to Roll Call.

The Rhode Island Democrat -- who is not running for re-election -- was in high spirits, calling President Obama "the best president ever," the source told Roll Call.

When the source told Kennedy he reminded him of his uncle, President John F. Kennedy, the lawmaker guffawed, "Oh, yeah! Good one."

Earlier in the night, Kennedy was honored by the nonprofit N Street Village, which helps homeless and drug-addicted women.

In his speech, he discussed the 2006 incident in which he crashed his car into a barricade on Capitol Hill. Shortly after, he entered rehab.
