When Sen. Trent Lott decides which GOP presidential candidate to support in 2008, it apparently will not be Sen. Bill Frist, the Tennessee Republican who Lott says betrayed him at a low moment in his political career.

Asked Sunday on NBC’s “Meet the Press” whether Frist, who challenged and succeeded Lott as Senate majority leader in 2002, has the character to be president, Lott paused before answering.

“I think I’d have to think about that,” said Lott, R-Miss.

Lott said “a lot of good people out there” are thinking about whether to run and that “I probably would lean toward some of the others, let me just put it that way.”

In a new book, “Herding Cats, A Lifetime in Politics,” Lott fingers Frist as one of the “main manipulators” in the events the led to Lott’s fall from power.

Lott lost the majority leader’s post in 2002 after making racially tinged remarks at a 100th birthday party for Republican Sen. Strom Thurmond of South Carolina, a one-time segregationist.

Lott wrote that Frist’s actions amounted to a “personal betrayal.”

Frist “didn’t even have the courtesy to call and tell me personally that he was going to run,” Lott wrote.
