“If Cain actually looks like he will win the nomination, you can be sure these woman will come out of the woodwork.”
Maybe so but the effect will be greatly diminished by then. In a way it will be old hat.
The media is less influential than they used to be. Internet and social media has changed how people get their news. Most people I know, weigh whatever they see on TV against whatever they follow online like Daily Caller, Right Scoop. Plus, there is a rather captive audience on Facebook. They are watching streaming feeds from their friends and the truth can spread nearly as fast as the rumor!
Even if they try and trot this out again, I think it will be buried pretty fast.
The media is not as they think they are.
