Right, Wayne.
However, as I asked above, why did Michael tip his hand to Geary? Vito admonished Sonny to not let anyone outside the family know what you are thinking. Michael apparently disregarded that sage advice by giving his emotion based response to Geary. I think it would have been much better for Michael to simply have remained quiet and allowed Geary to think that his blackmail worked. By responding to Geary he may have prompted Geary to marshall his senatorial forces.
I think it was just arrogance/conceitedness on Michael's part, honestly. Just like a "Who does this scumbag think he is?" kind of thing.
