WASHINGTON -- Not enough "star" power for Fred Thompson in a GOP presidential field that includes some of his friends? Whatever the case, the actor and former Tennessee senator is considering getting into the 2008 race.

Thompson, who plays district attorney Arthur Branch on NBC's drama "Law & Order," said, "I'm giving some thought to it, going to leave the door open" and decide in the coming months. "It's not really a reflection on the current field at all."

"I'm just going to wait and see what happens," Thompson added. "I wanted to see how my colleagues who are on the campaign trail do now, what they say, what they emphasize, what they're addressing, and how successful they are in doing that, and whether or not they can carry the ball in next November."

Thompson, 64, said he was pondering a run after former Senate Majority Leader Howard Baker and other Tennessee Republicans began drumming up support for his possible GOP candidacy, citing his conservative credentials.

"I think people are somewhat disillusioned. I think a lot of people are cynical out there. I think they're looking for something different. ... and I think that they're going to be open to different things," he said.

"It will be interesting to me as I listen to people and learn and watch what's going on and what's the reaction, and the poll numbers and so forth, as to whether or not my instinct on that is right."
