Like most of the rest of the Susquehanna Valley, Dauphin County was once reliably Republican, and the commissioner majority and all county row offices remain in Republican hands. However, there has been a decided shift toward the Democrats in recent years, who overtook the Republican countywide registration during the summer of 2008. Bob Casey Jr. carried the county in the 2006 Senate election when he unseated Rick Santorum. According to the Dauphin County Board of Elections, in 2008 Barack Obama became the first Democratic presidential candidate to carry Dauphin County since 1964, receiving 9.0% more of the vote than John McCain. The other three statewide winners (Rob McCord for Treasurer, Jack Wagner for Auditor General, and Tom Corbett for Attorney General) also carried Dauphin. [3]
