Frankly, she's totally right and probably unfairly condemned by the McCain campaign for her truthful statement that Plain, McCain, Biden, and Obama probably would suck in the CEO chair.
Yanking her GOP talking head credentials, however, sends the message that those with skills in business are going to be good executives in public office and vice versa. That's simply not so. Campaign slogans along the lines of "Candidate X . . . A Businessman, not a politician," have long irked the bejesus out of me.
