It's that time for newspapers to make their endorsements for the presidential race. Most do it in their Sunday editions (biggest readership) and post them online on Saturday. The good folks at Editor & Publisher track these things each year and so far this year quite a few papers that endorsed Bush in 2004 have now endorsed Obama. The big news this weekend: the Chicago Tribune, which has never endorsed a Dem for president, endorsed Obama, as did the LATimes, which has had a policy of not endorsing for more than 30 years. In the way of swing state newspapers, the Denver Post, which had endorsed Bush in 2004, moved to Obama.
E&P has the rundown.
Now, do these endorsements actually a matter? That's unclear. It seems that there's at least some correlation, but it may or may not be causation.
