That’s how many counties voted for President Barack Obama in the 2008 election after backing President George W. Bush in the 2004 election.

Of these 336 “Obama-Bush” counties, 107 are in the nine states where Obama and Romney have focused most of their attention and campaign spending before the Nov. 6 election.

There are four such counties in Florida, the biggest politically competitive state, including Hillsborough (Tampa) and Pinellas (St. Petersburg).

Hamilton County, Ohio, which includes Cincinnati and some suburbs, backed Obama by about 30,000 votes four years after siding with Bush by about 23,000 votes, Bloomberg’s Julie Hirschfeld Davis and Mark Niquette report in a story about the presidential campaigns’ voter contact efforts in Hamilton.

Obama campaigned Saturday in Prince William County, Virginia, which is near Washington, D.C., and is among 18 Virginia counties or cities that voted for Obama and Bush. On Saturday, Romney stopped in Arapahoe County near Denver, one of seven Obama-Bush counties in Colorado.
