So far it looks like of the capitals in counties Romney won;
Obama won Salem, Salt Lake City, Phoenix, Helena, Lincoln, Topeka, and Annapolis or at least I think it safe to assume he won these even if they were close.
Charleston, Boise, and Springfield still seem unclear to any clarification would be great.
It looks like Romney won Carson City, Cheyenne, Bismarck, Pierre, and Jefferson City, so he won anywhere between 5-8 state capitals.
I wonder if the 2012 results in these state capitols were ever determined or calculated. Of the cities I bolded, I would assume Obama won all three, thus leaving Romney with five state capitols. Biden actually won Marion County (Salem), Maricopa County (Phoenix), Shawnee County (Topeka), and Anne Arundel County (Annapolis) last year, all of which Obama lost twice, so he almost certainly outperformed Obama in these cities.
