Well, she has some good company on this one.

Today, the Senate voted 83 to 7 to cut off all federal housing funding for ACORN and ACORN Housing Corporation. If it passes the full Congress, the largest loan counseling operation for low and moderate income families in the entire country will die. AHC has counseled 50,000 people (primarily people of color) in the last year to help them avoid foreclosure.

That means that not only did McCaskill throw ACORN under the bus, senators like Schumer, Feingold, Merkley, Brown, and so on did the same thing.

Full roll call vote here.
