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.

Shortly after Obama's happy inaugural, eyebrows rose slightly upon word that, 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.

For an ordinary American, that would likely raise some obvious tax liability questions. But like Emanuel, the guy overseeing the IRS now is another Obama insider, Tim Geithner, who had his own outstanding tax problems but skated through confirmation anyway by the Democratic-controlled Congress. ...

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.

Probably just a crazy coincidence. But you'll never guess who was the chairman of that Democratic Congressional Campaign Committee dispensing those huge polling contracts to his kindly rent-free landlord.
