The Chicago Tribune officially announces its backing of George W Bush here. They supported Bush in 2000 also, as did the Sun Times, IIRC. So I pretty much expected it, although I don't fully understand it; my opinion of the Trib is that it's generally liberal, and Chicago is obviously a liberal town. But I'm not going to look gift horses in the mouth :). Via LGF.
60:40 odds the Sun Times follows suit. Or maybe they have already; I'll do a quick search and get back to you on that.
