John Spencer of the West Wing dead

I know, another actor has died, BFD. I don't know John Spencer but I did like the show he is...was in. The West Wing. Great show that found its second wind this season. John Spencer played the character Leo McGarry who was the Barlett Chief of Staff, then Democratic VP candidate. Its a shame to see him go and condolences to his family. The show will not be the same without him.
