While Clinton County has historically been Republican like the rest of central Pennsylvania, Democrats captured the registration edge in early 2008. Each of the three row-office statewide winners carried Clinton in 2008. In 2006, Democrat Bob Casey Jr. received 54% of its vote when he unseated incumbent Republican US Senator Rick Santorum and Ed Rendell received 56% of the vote against Lynn Swann. The conservative tendencies of the county were again reestablished in 2008 when then-Senator Obama lost the county vote 48% to John McCain's 51%. This was followed in 2010 with U.S. Senate candidate, Republican Pat Toomey, receiving 59% to 41% for Democrat Joe Sestak. In 2012, Mitt Romney carried the county 55% to President Obama's 43%, while incumbent Democratic Senator Bob Casey, Jr. received 44% to his Republican challenger, Tom Smith's 53%.^[16]
