They will say since Cain talked about it, the condifentiality portion is broken and seomone will offer enough money to make it worth their while...and then watch them come forward and try and refute whatever it is Cain has said.
Then he will fall back on the records of the investigation itself.
In the end, my guess is the attempt is going to just further galvanize Cain's support.
It is already doing so and it will backfire on the left and RINOs.
They will pull out all the stops,
because Cain is THE guy that they don’t want facing 0bama.
