Blaming Rahm Emanuel? Actually, Put Barack Obama in the Crosshairs

Here's the new ad buy from the Progressive Change Campaign Committee, "Rahm = Weak":

I don't recall interest groups targeting a chief of staff with attack ads before. But ABC News' David Chalian suggests that Emanuel may want to return to public office, so progressive groups are turning up the heat, indirectly in this case, since the ultimate target should be the president. He's the one who's causing grassroots disillusionment with the Democratic agenda -- that is, Obama and the simply lame Pelosi-Reid Congress.
