Newcomer Gabriel Gomez to face off against veteran Edward Markey

Gabriel E. Gomez, a businessman making his first run for higher office, won the Republican senatorial primary Tuesday, scoring an upset victory that has the potential to draw major national interest as he prepares to face Edward J. Markey, a veteran congressman who rolled to a win in the Democratic contest.

Gomez, a 47-year-old private equity ­investor from Cohasset, used his fund­raising advantage to soundly defeat Michael J. Sullivan, a former state and federal prosecutor considered the front-runner for the GOP nomination. Daniel B. Winslow, a state representative and former district court judge, ran a distant third.
