We already knew that BP and its folks were significant contributors to the record $750-million war chest of Barack Obama's 2007-08 campaign.
Now, we learn the details of a connection of Rahm Emanuel, the Chicago mayoral wannabe, current Obama chief of staff, ex-representative, ex-Clinton money man and ex-Windy City political machine go-fer.
... as a House member, Emanuel had lived the last five years rent-free in a D.C. apartment of Democratic colleague Rep. Rosa DeLauro of Connecticut and her husband, Stanley Greenberg.
Greenberg's consulting firm was a prime architect of BP's recent rebranding drive as a green petroleum company, down to green signs and the slogan "Beyond Petroleum."
Greenberg's company is also closely tied to a sister Democratic outfit -- GCS, named for the last initials of Greenberg, James Carville, another Clinton advisor, and Bob Shrum, John Kerry's 2004 campaign manager.
According to published reports, GCS received hundreds of thousands of dollars in political polling contracts in recent years from the Democratic Congressional Campaign Committee.
