It must be very lonely being the last flat-earther.

Sen. Jim Inhofe of Oklahoma, committed climate-change denier, found himself in just such a position Tuesday morning as the Senate environment committee, on which he is the ranking Republican, took up legislation on global warming. Sen. Lindsey Graham (R-S.C.) was in talks with Democrats over a compromise bill -- the traitor! And as Inhofe listened, fellow Republicans on the committee -- turncoats! -- made it clear that they no longer share, if they ever did, Inhofe's view that man-made global warming is the "greatest hoax ever perpetrated on the American people."
