Fred Thompson: What's Up With That?

Former presidential candidate Fred Thompson gave a fiery and well-received convention speech on Tuesday night.

He follows it up today by announcing Fred PAC--a PAC dedicated to the election of conservative candidates.

Pardon me for scratching my head over the new, energized Fred Thompson...when he campaigned for President in Iowa...he seemed distracted and bored. Even as the media was asking if he was the savior of the GOP, I was attending speeches in which he seemed completely disengaged.

So what's up now?
