He's a real estate investor from suburban Philadelphia and is campaigning with Scott Wagner, who won the primary in the PA governor's race.
Along the way, Wagner pumped more than $10 million of his own cash into his campaign, and he spread hundreds of thousands more around the state since a year ago to boost GOP committees and candidates.
With almost 99.5 percent of voting districts reporting statewide, John Fetterman won the Democratic nomination for lieutenant governor.
Wagner defeated two first-time candidates from the Pittsburgh area, Paul Mango and Laura Ellsworth, surviving weeks of Mango's sharp-elbowed attack ads that painted Wagner as sleazy, greedy and a "deadbeat dad". Pennsylvania first started allowing lieutenant governors to serve a second term in the 1970s.
On Tuesday, Pennsylvania voters chose Braddock Mayor John Fetterman as the Democratic candidate to run alongside Gov. Tom Wolf in the November general election, ousting incumbent Lt. Gov. Mike Stack.
On the Republican side of the ballot, Jeffrey Bartos grabbed the GOP nomination from Kathleen Coder, with 47 percent and 20.8 percent of the vote, respectively.
Fetterman had made a failed bid in 2016 for the U.S. Senate.
