Agree totally. I fear that Cain really has made a huge error in jumping on this. I hope he can find some way to admit he was wrong, convincingly, unlike Bachmann with the vaccine/mental health, Perry with the college tuition, Mr.Newt with his ex-wife, Romney with healthcare, ...
You have a spot on analysis of most politicians though. When they say or do something wrong, it is hard many times for them to come to grips with what they did wrong or know how to appropriately go forward.
A politician’s strength can be seen by how they handle hurdles such as what you mentioned.
Since Cain has no real political experience other than mostly speeches and debates, it is unfortunate for us that we have Cain’s only political record of rights and wrongs through his campaign talk. However, for those who are interested in him and think he is worth putting in office to see how he does in politics, at least we have his words and media reactions to go on.
