According to Editor & Publisher magazine:
Barack Obama picked up at least 17 newspaper endorsements this weekend, including six in swing states Wisconsin, Pennsylvania, Ohio, North Carolina, and Missouri. John McCain, as far as we know, gained just two.
The Wisconsin State Journal and The Sun of San Bernardino had backed Bush in 2004. The St. Louis Post-Dispatch called Obama’s opponent, John McCain, “the incredible shrinking man” who had made a horrific pick for his running mate.
Backing Obama: In Ohio, The Blade in Toledo and the Dayton Daily News; the Pittsburgh Post-Gazette, St. Louis Post-Dispatch, The Tennessean of Nashville, the Wisconsin State Journal. the Asheville (N.C.) Citizen-Times, and in California the Fresno Bee, Sacramento Bee, Contra Costa Times, The Herald of Monterey, The Santa Cruz Journal and The Sun of San Bernardino (which had picked Bush over Kerry), plus the New Bedford Standrd-Times in Massachusetts.
Joining the Obama team in battleground states were the Muskegon (Mich.) Chronicle, the Lehigh Valley (Pa.) Express-Times and Springfield (Ohio) News.
McCain registered two pick-ups: The Wheeling News-Register in West Virginia and the Napa Valley Register in California.
