LOL! Relying on Wikpedia's leftist editorializing to discredit Thompson?
Look at Thompson's lobbying history -- it is universally in favor of deregulation, period. As in, get the federal government out of regulating things it has no business dealing with in the first place.
Deregulation generally works. To point to one failure that deregulation may have allowed to happen does not invalidate that deregulation was still the right thing to do.
In any case, Thompson is hardly a 'citizen politician.' He is very much a part of the DC power structure.
As for his winning attributes, listen to Lamar Alexander: EARTH TO LAMAR: FRED THOMPSON LOOKING THE PART AIN'T ENOUGH (41-second video FLUB)
What if Thompson's sole purpose is to give McCain the nomination by skimming off just enough conservatives from Rudy? (NB: gross is net, i.e., McCain has no conservative support to lose.) FRED'S GREATEST ROLE?: an alternative theory of Senator Thompson's not-yet candidacy
