Let me 'splain this again: If you have something questionable or potentially damaging in your past, just assume that at some critical time in your career, your business or your campaign, it will come out -- sometimes accidentally, sometimes on purpose. Decide NOW what you can and will say, practice it out-loud, polish it, and be prepared.
At ICM we recommend you tell your side of what happened/or didn’t, say you made a mistake (if you did) and have been working to make it right (if you have) and say you’re sorry – and mean it.
It won’t always stop the damage from eating away at you or your organization, but most of the time it will be a one-day story and then disappear. It’s when you are not forthcoming, your enemies/opponents can and will keep chipping away at your integrity, reputation and name.
I know, you want to know what we would have suggested Mr. Cain say when the issue first came up.
Then when asked about it again, simply be prepared to say: I answered that question yesterday (or when ever) do you have anything you want to ask me?
