A still from an American Energy Alliance ad. (Click to watch.)

Here’s an astonishing statistic, brought to us by Bloomberg:

In April, 16,991 negative ads aired in various parts of the country and 13,748 of them — or 81 percent — focused on energy, according to data provided by New York-based Kantar Media’s CMAG, which tracks advertising.

Energy? Really?

The details of the story make clear that the vast bulk of these negative energy ads are attack ads directed at Obama, purchased by big PACs — Americans for Prosperity, American Energy Alliance, Let Freedom Ring, Crossroads Grassroots Policy Strategies — awash in Big Oil money.
