via Human Events, the return of the Fred! to the national media is part of the McCain team's campaign strategy. Thompson will apparently be heavily involved with the Supreme Court nomination and vetting process in any potential McCain administration.
"In a McCain campaign conference call with reporters yesterday on last week’s Supreme Court decision on terrorist detainees at Guantanamo Bay, Cuba, Thompson -- without claiming such status -- played the role of a prominent McCain adviser."
Best news I've heard today, but I would really like to hear Fred having an even more prominent position, perhaps in the cabinet. Personally, I like the sound of Attorney General Thompson.
