This site – http://www.wheretodoresearch.com/Political.htm#Endorsements – gives lists of newspapers that endorsed Bush and Gore, respectively, in 2000. Bush’s list is a lot longer. I’ve found no comprehensive listing of this year’s endorsements. Does anybody know if any newspaper that endorsed Bush in 2000 has changed its mind and endorsed Kerry this year? Conversely, have any newspapers that endorsed Gore in 2000 decided to back Bush this year?
The Tampa Tribune 
Bush’s hometown paper, the The Iconoclast, endorsed Kerry after endorsing Bush in 2000.
Related question: does anyone know who The Economist magazine is endorsing this year? In 2000 it was Bush, I’m curious which way they’ll go this year, but I haven’t had time to read it in the last few months
ewwww look at me, I read The Economist
Here’s a couple of sources jshore just linked to in a GD thread ("We’re in the home stretch: Election predictions " – http://boards.straightdope.com/sdmb/showthread.php?t=280703&page=1&pp=50):
From Reuters, http://www.reuters.com/newsArticle.jhtml?type=topNews&storyID=6521523:

Well, the *Lone Star Iconoclast * didn’t begin publication until December of 2000, so if it endorsed President Bush it was a little late (unless the Supreme Court was on their distribution list 
). And don’t expect too many more endorsements, since most of their advertisers have pulled out and the few readers they had (about 400) are treating the paper like a hot cowpie on a cold morning.
Hmmm…what about the Denver Post? I notice that they specifically mention the Denver Rocky Mountain News and if one supports a candidate, than it would likely mean that both of them do. However, the Post is not mentioned at all and I would think if they were to choose between which one to name, that’d be it (since it’s the morning publication and the major masthead on Sunday - the RMN only has Saturday).
The Seattle Times endorsed Bush in 2000 and Kerry in 2004.
The Portland *Oregonian *endoresed Bush in 2000, and is endorsing Kerry in 2004.
Sorry, a closer read of the article says “the publishers of the Lone Star Iconoclast endorsed Bush in 2000”. I guess they were working for a different paper at the time. My bad.
