Our politicized EPA seeks to undemocratically impose costly carbon regulations on the country.

The EPA has now formally made an "endangerment finding" on CO2, which will impose the command-and-control regulations of the Clean Air Act across the entire economy. Because this law was never written to apply to carbon, the costs will far exceed those of a straight carbon tax or even cap and trade—though judging by the bills Democrats are stitching together, perhaps not by much. In any case, the point of this reckless "endangerment" is to force industry and politicians wary of raising taxes to concede, lest companies have to endure even worse economic and bureaucratic destruction from the EPA.

And David Letterman thinks he was a blackmail victim.
