Hagel is a mad man. Best thing he can do is voluntarily resign from the Senate and enter a facility for some sort of rehabilitation.
I think it more accurate that Hagel is an ambitious man, without the judgment to realize his ambitions. Having said that, his need for attention causes him all to often to indulge in a circus act routine, with him playing role of the clown. I am sure Hagel would disagree with my uncharitable characterization, and perhaps I am being too harsh.
