To avoid incoming criticism, members often fly in group formation -- with members of the other party. Say the words "Paris Air Show," and partisan rancor melts. This year, Sens. Daniel Inouye, D-Hawaii, and Richard Shelby, R-Ala., went with four other senators. In 2007, then-Sen. Ted Stevens, R-Alaska, led an entourage that ran up a $121,000 tab on the ground.
Democrats have led both houses since January 2007. Is Congress more ethical? Is Washington spending tax dollars more carefully? Are global warming's true believers curbing their own emissions?
Sure -- when they get caught.
