Sorry, but that doesn’t cut it.
Being President is much harder than these “allegations”. If his wife wasn’t up to this she wasn’t up to being first lady when the going gets tough.
It all smells of an out for him.
I just think that if this is true Cain should have talked about his run for the Presidency with his family, and made a clear decision to not run, or to fight as hard as possible to win the nomination regardless of the vicious racist attacks that were obviously coming. You have that talk before you run, not several months into your campaign. You know being a black Republican you're going to get it literally as bad as is possible, considering you're not only seen as a threat in one race, but to an entire demographic that democrats depend on to win elections. Cain said he was ready for the expected “high-tech” lynching that was to come.
It's also at the point that while Cain may delay the investigations, it's going to come out if he did anything which I am doubting based on the fact it hasn't already come out. All this would do is delay things a little. He's not even going back to live a more private life, but is going to be very vocal, and in the public eye. I don't know what's going on, but I honestly couldn't care less about his personal life, because it's political issues he would be affecting my life with if President.
