This timetable may be slightly warped, so correct me if I'm wrong. This once practicing Catholic came out as an atheist.
Then he became a shill for Hillary Clinton.
When that (personality of a) water moccasin could not get elected, he decided it best to shill for Tom Perez, Keith Ellison and the Democrat Party.
Along the way he became unreadable (possibly) but insufferable (no doubt).
No possibly about it. To be readable you need to be able to say things well and have something that others a willing to hear. Will used to be an undisputed and barely matched master at the first. Used to be. When he was defending Reagan on good terms with Buckley he wasn't bad on the second, but he has lost both his skill and his taste and is now just another piggy at the trough.
