Whats happened to Joe Liebermann? Is he senile? Brain aneurysms?

Time magazine Baghdad bureau chief Michael Ware on Morning Sedition this morning:

I and some other journalists had lunch with Senator Joe Lieberman the other day and we listened to him talking about Iraq. Either Senator Lieberman is so divorced from reality that he's completely lost the plot or he knows he's spinning a line. Because one of my colleagues turned to me in the middle of this lunch and said he's not talking about any country I've ever been to and yet he was talking about Iraq, the very country where we were sitting.
