Remember Mary Bono?  She's been in Congress ever since her husband, the legendary Sonny Bono, skied into a tree and died in 1998.

Well, RadarOnline.com just posted pictures of Mary having her tatas tongued by a campaign donor named Edra Blixseth four years ago.  A witness says, quote, "Mary was partying hard.  She was blitzed and clearly having a great time."
