Now, Rep. Joe Barton is taking the outrage to a new level. This morning on America's Newsroom, the industry-friendly Texas Republican accused the EPA of suppressing the report, and declared that "just as Nixon had Watergate, Obama now has Carbongate to deal with."
(Note that Barton called Carlin "a scientist at the EPA." In fact, Carlin has worked for the agency since months after its founding in 1971, but he does not hold an advanced degree in any natural science, and he has always worked as an economist.)
So just to compare: Watergate involved the cover-up of a criminal enterprise directed from the Oval Office. "Carbongate" involves the EPA ignoring a scientific study by a non-scientist that it never commissioned and which hasn't been published in any scientific journal. There may be better comparisons.
