Dubow’s mother, Phyllis Beck, was the first woman elected to the Superior Court in 1983.
With 99% of the state’s 9,173 precincts reporting, Dubow has picked up 53% of the vote, seeing off GOP nominee Emil Giordano.
Dubow, 56, will serve a 10-year term beginning in January 2016. Superior Court judges can retain their seats until the age of 70 under PA law.
Dubow will be one of nine women on the Superior Court come January, after David Wecht and Christine Donohue won promotions to the PA Supreme Court.
Democrats had a very successful night, winning all three openings on the Supreme Court and an opening on the PA Commonwealth Court.
