The Black Gorbachev

From the recent article, "Barak Obama's 100 days of denial":

Barack Obama, who is already being lightly derided as a ‘Black Gorbachev’ in Russian circles . . .

What does that even mean?  Seriously?  In fact the entire article is tainted by an immature tone that is more reminiscent of Perez Hilton than any form of respectable journalism.
