Mantoloking is one of the most consistently Republican jurisdictions in the state of New Jersey. After New Jersey native Woodrow Wilson carried the borough in its inaugural election, no Democratic presidential candidate has done so again. Even as New Jersey has trended Democratic since the 1990's, Mantoloking has remained largely Republican, with 2016 and 2020 Republican nominee and president Donald Trump carrying the borough by over 25 points in both of his campaigns. Prior to Trump, all of the preceding 21 Republican nominees for president from Herbert Hoover in 1932 to Mitt Romney in 2012 won Mantoloking by a margin of at least 50 points, with 14 of them earning 80% of the vote, and Thomas Dewey in 1948, Dwight Eisenhower in 1956, and Richard Nixon in 1960 and 1972 each winning 90% of the vote.
