U.S. Sen. Jim Inhofe (R-Okla.) once called global warming "the greatest hoax ever perpetrated on the American people." "The Greatest Hoax" is also the title of his new book, which he was promoting on Rachel Maddow's show last night.

As reported by Raw Story, Inhofe "said Thursday night that environmentalists spent far more money lobbying than the energy industry."

This is a ridiculous claim. As you can see from the chart below, when you look at the actual data, the electric utilities and oil and gas industries alone far outspend environmental groups on lobbying and campaign contributions.
