Republican Congressman Joe Barton (once named "Smokey Joe" by the editorial pages of the Dallas Morning News for his loyalty to anything with a smokestack) says he favors Dingell.
From today's Dallas Morning News:
Mr. Barton, the top Republican on the energy committee, said both men are "very smart and very aggressive." But Mr. Barton said he favors Mr. Dingell.
"Dingell tends to be more bipartisan," Mr. Barton said. "I don't have
any reason to fault John Dingell in his chairmanship."
