Maddow: Anonymous corporate donors firing up as new campaign issue

Excellent piece by MSNBC commentator Rachel Maddow on a new message gaining ground among Democrats.

The big corporate donors are contributing anonymously to campaigns in support of candidates and ballot measures.

Evidence is building that many voters are concerned about these money sources and want to know who is funding what. In particular, the possibility that foreign multi-national companies may be contributing to the U.S. Chamber of Commerce's political ad campaigns is of major concern.
