A young state representative from Philadelphia has beaten three rivals, including a former congresswoman who is now Chelsea Clinton's mother-in-law, to win the Democratic nomination for an open seat in the U.S. House of Representatives.
Early returns showed Brendan Boyle winning Tuesday's Democratic primary in Pennsylvania's 13th District, virtually assuring him of becoming the successor to Allyson Schwartz.
The district straddling Philadelphia and Montgomery County is heavily tilted toward Democrats.
Campaign fundraising appearances by Bill and Hillary Clinton failed to help former U.S. Rep. Marjorie Margolies in her bid to recapture the seat she lost 20 years ago after only one term in office.
Boyle was the only one of the four candidates from Philadelphia.
