I think this may backfire because it’s too obvious a partisan hit piece using anonymous sources and unsubstantiated gossip. This seems to be the case because Cain has held his standing in all the polls.
Probably.Republicans (who are primary voters) are the ones least impressed with the unsourced attack on Cain. In the general election you need independents, too - but then, November 6, 2012 is a year away. That is time enough to make these charges old news indeed, absent any real beef. And even if there turns out to be something, time enough to place it in context of how little came of so much more substance in the case of Bill Clinton.
