I think John Fund at the OpinionJournal Political Diary has the goods on a good Democrat that President Bush could appoint. Louisiana Senator John Breaux:
President Bush is in hot pursuit of a Democrat for his Cabinet. Transportation Secretary Norm Mineta, a former Democratic congressman from California, is expected to leave and Mr. Bush wants to make a bow towards bipartisanship as his second term begins.His top prospect is John Breaux, retiring in January as a Democratic Senator from Louisiana. Mr. Breaux has a genuinely moderate voting record and bravely co-chaired a Medicare commission in the late 1990s that advocated free-market reforms. He could fit in as secretary of either Health and Human Services or, since Louisiana is a major oil and gas state, at Energy.
Mr. Breaux has told friends that at age 60 he feels he has enough years to try one more career. While he might be tempted to take up an offer from President Bush (with whom he has good relations), the major obstacle is that Mr. Breaux may be tired of government, having been first elected to the House of Representatives in 1972 at age 28. Watch for Mr. Breaux to be invited to the Oval Office for some straight-talk lobbying.
