I’ve found three more newspaper endorsements: the Omaha World-Herald, the Dallas Morning News, and the North County Times. All three papers endorsed Mitt Romney and endorsed John McCain in 2008. The early pattern appears to be that newspapers that endorsed Obama in 2008 are endorsing him again, newspapers that endorsed John McCain are endorsing Mitt Romney, and newspapers that didn’t endorse anybody in 2008 but have conservative readerships are endorsing Mitt Romney.
I’ll post more endorsements as I find them. If you know of any other newspaper endorsements, please identify them in comments.
