Word reached me a little while ago that John Spencer of ''The West Wing'' has died. It's quite a blow. You can see my admiration of his work and his character in my recent ''Journey of Leo McGarry'' post. I also had a chance to talk to John several times over the years, and not just about ''The West Wing,'' and he was one of the nicest guys in the world. At the moment, I don't know what ''West Wing'' will do without Leo, and I pretty much don't care. Instead, I'm saddened by the loss of such a terrific actor, and glad I had the chance to know him a little.
