Forget the latest polls showing Gingrich, Cain and Romney all in the top tie and neck-and-neckr. People weren't prepared to let Perry get away with a debate gaffe forgetting something fundamental. Cain just committed an equally bad political sin - looking lost in answering a question.
So forget the polls out today - a week from now, barring more surprises, it will be only Gingrich and Romney in the top tier. After this, the media will see to it that everyone knows Cain is not ready for prime time.
Foreign policy is a key component of the presidency. Cain may have some great ideas but it has become apparent that he's not ready for every aspect of the presidency.
