Back Again - May 2, 2012

ANNOUNCER: They just keep coming back. Secret money, attacking Claire McCaskill. These big oil and insurance companies don't want you to know who they are, but here's what they want to do: end Medicare as we know it, cut student loans for college and keep giving taxpayer subsidies to the big oil companies. But Claire McCaskill will fight them – always has, always will.

MCCASKILL: I'm Claire McCaskill and I approve this message.
