Lebanon County has been a Republican Party stronghold for the vast majority of its history. The only two elections Republican presidential candidates failed to win the county in from 1888 to the present were when third-party candidate & former Republican president Theodore Roosevelt won it thanks to a split Republican vote in 1912 & as a part of a national landslide victory by Franklin D. Roosevelt in 1936. As a testament to how Republican the county is, FDR in the two following elections & Lyndon B. Johnson in 1964 are the lone Democratic candidates since 1936 to crack forty percent of the county's votes.
The county is located in the 9th congressional district, represented by Dan Meuser, Republican.
All of the county falls within the 48th Senatorial District. The seat is currently held by former DA Dave Arnold
The county is divided into the 101st, 102nd and 104th Pennsylvania House Districts.
The county is governed by three commissioners, who are elected every four years from a slate of four candidates (two Democrats and two Republicans). Other elected officials include County Controller, Sheriff, Coroner, Prothonotary and Clerk of Court, Recorder of Deeds, County Treasurer, and Jury Commissioners.
As of November 2008, there are 82,394 registered voters in Lebanon County.
The county has a history of being one of the most Republican counties in Pennsylvania. No Democratic Presidential candidate has won Lebanon County since 1936, when Franklin Delano Roosevelt narrowly carried it even as he won re-election in a landslide nationally. The only other time in the 20th century that the county didn't support a Republican was in 1912, when Theodore Roosevelt carried it on the Bull Moose ticket.
Republicans are no less dominant at the state and local level. The row offices and all but one county commission seat are held by Republicans, and there are no elected Democrats above the county level.
