Northampton is one of the seven counties in Pennsylvania which has adopted a home rule charter. Voters elect an Executive, a nine-person Council, a Controller, and a District Attorney. The Executive, Controller and District Attorney are elected at-large by all voters in the County
Five members of the council are also elected at-large. The other four members of the council are elected from single-member districts. This weighted structure of government favors the majority of voters, but it does allow for representation of minority groups, if they live within a compact voting district. The Row Officers are nominated by the county executive and approved by county council.
As of December 2020 there were 227,400 registered voters in Northampton County
In recent decades, Northampton has been identified as one of Pennsylvania's "swing counties," with statewide winners carrying it in most cases; since 1952, it has gone to the statewide winner in the presidential election. All five statewide winners carried it in November 2004 and all four statewide Democratic candidates carried it in November 2008, with District Attorney John Morganelli doing well there despite losing statewide to incumbent Attorney General Tom Corbett. The Democratic Party has been dominant most of the time in county-level politics in recent decades. In 2014, John Brown bucked that trend when he became the only Republican in the 21st Century to be elected Northampton County executive, a harbinger of Donald Trump winning the county and the state at the presidential level in 2016. Lamont McClure retook the county executive position for the Democrats in 2018; Joe Biden won Northampton County and Pennsylvania in 2020.
Municipal elections were held across Pennsylvania in November, 2019, and results in Northampton County were plagued with problems caused by newly purchased machines, The ExpressVoteXL, sold by the manufacturer Election Systems & Software (ES&S) as "a luxury “one-stop” voting system." According to the New York Times and other publications, it was a few minutes after the polls closed on Election Day when panic began to spread through the Northampton county election offices. Vote totals in one judge’s race showed one candidate, Abe Kassis, a Democrat, had just 164 votes out of 55,000 ballots across more than 100 precincts. Some machines reported zero votes for him..
The voting system, used in numerous Pennsylvania jurisdictions, combines a touch screen with a paper ballot backup. County officials determined the results by counting the paper ballots, which showed Mr. Kassis had won by 1,054 votes. Unofficial results were announced at 6AM on November 6th. The election results were certified following a canvass and audit. No challenges to the election results were filed.
