It has been represented by Republican Chris Smith since 1981, the second-longest currently serving member of the US House of Representatives and the longest serving member of Congress from New Jersey in history. Although the 4th district had a presence in Mercer County for decades, it lost its two towns in the county (Hamilton and Robbinsville) following the redistricting process in late 2021, which was based on the 2020 census.
