Shadowy players in a new class war

Today's column by E.J. Dionne is great. Here's an excerpt:

...corporations and affluent individuals are pouring tens of millions of dollars into attack ads aimed almost exclusively at Democrats. One of the biggest political players, the U.S. Chamber of Commerce, accepts money from foreign sources.

The chamber piously insists that none of the cash from abroad is going into its ad campaigns. But without full disclosure, there's no way of knowing if that's true or simply an accounting trick. And the chamber is just one of many groups engaged in an election-year spending spree.

This extraordinary state of affairs was facilitated by the U.S. Supreme Court's scandalous Citizens United decision, which swept away decades of restrictions on corporate spending to influence elections. The Republicans' success in blocking legislation that would at least have required the big spenders to disclose the sources of their money means voters have to operate in the dark.
