Like most of the rest of the Susquehanna Valley, Dauphin County was once reliably Republican. However, there has been a decided shift toward the Democrats in national and statewide elections 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.  It was also only the third time Dauphin County had supported a Democrat for president since 1936. Obama won Dauphin with a slightly reduced majority in 2012, while Hillary Clinton won it with a narrow plurality in 2016. It is now one of the few blue counties in traditionally heavily Republican south-central Pennsylvania.
Nonetheless, the GOP still holds all of the county row offices, as well as a majority on the county commission. All but one state house seat is in Republican hands, as well as both of the state senate seats and all three congressional seats. Most local elected officials are also Republican, by a margin of 3 to 1. This is because most Democratic strength is concentrated in Harrisburg, while the suburbs and rural areas remain heavily Republican.
