Campaign
Kennedy was overwhelmingly popular in Massachusetts and the 1958 elections were a wave election favoring the Democratic Party. Celeste's campaign was poorly funded but the candidate worked 17-hour days, running his campaign out of his law offices and attempting to frame the race as one pitting a working-class child of Sicilian immigrants against "that millionaire Jack Kennedy."

The Kennedy campaign had bought and produced thousands of pieces of campaign material with the slogan "Be Proud of Your Vote!" but scrapped them after Celeste's nomination, as Senator Kennedy's father Joe thought the slogan could alienate Italian-Americans and divide the state on ethnic lines.

Results
Kennedy defeated Celeste by a margin of 874,608 votes; this represented the largest margin of victory in a statewide Massachusetts election up to that point.
