So what WAS the evidence that Cain was guilty? NOTHING.
Sometimes Republicans are their own worst enemies.
Cain quit because he knew it was hurting the Republican campaign, as well as the fact he couldn’t get his message out any more.
No doubt that the MSM tried to get him. Regardless whether there was an affair or not, Cain did this to himself when he thought such action wouldn't be an issue in presidential campaign. He should have cleaned up his closet of anything that might have been an issue and came clean to his wife ad his advisers before he ran.
