Thompson's political origin as a protege of Sen. Howard Baker, leader of the Tennessee GOP's more liberal wing, prompted hard-line Senate conservatives to consider him a little too liberal. Actually, his lifetime Senate voting record as measured by the American Conservative Union was 86 percent. It would have been close to 100 percent except for his repeated votes supporting McCain's campaign finance reform. None of the big-three Republicans has been so consistently conservative as Thompson on tax policy, national security and abortion.
The principal complaint about Thompson concerns not his ideology but his work ethic. The rap is that he does not burn the midnight oil -- the identical criticism of Reagan, before and during his presidency. That carping may betray resentment that Thompson has emerged as a full-blown candidate without backbreaking campaign travel and tedious fund-raising.
Thompson's critics assert that, bored with his lucrative career as an actor, he has enjoyed his 15 minutes of fame created by a chance TV interview and will not really run. But he privately assures friends that this is for real. His performance on "Fox News Sunday" was no accident. He went on the program for the purpose of unveiling his possible candidacy.
Thompson did not leave public policy when he left the Senate. He has served on the U.S.-China Economic and Security Review Commission. He hardly knew Scooter Libby but felt he was getting a raw deal, appeared in his courtroom and helped raise money for his defense fund.
Friends bet Thompson will run. He clearly wants to try, and his wife, Jeri, is all for it. Seeking the best timing, he wants to avoid the pitfalls encountered by Democrat Barack Obama, who may have damaged himself by starting his campaign too quickly.
I met Fred Thompson in 1974 as Howard Baker's 31-year-old minority counsel on the Watergate investigation. I considered him cool, careful and conservative. He still is, and that is how he would run for president, which appears in the offing.
