Newspapers have been making presidential endorsements. Republican John McCain won the backing of his home state's largest paper, The Arizona Republic. The Chicago Tribune endorsed Chicago resident Barack Obama â€” the first time that paper has endorsed a Democratic candidate for president. And Obama received the backing from another paper you might not expect â€” the Anchorage Daily News. The state's largest newspaper was not swayed by the fact that McCain's running mate, Sarah Palin, is the state's governor.
