THE PLAYERS

THE STAKES

Pennsylvania's 13th District is up for grabs as Rep. Allyson Schwartz leaves her seat to run for governor. Journalist-turned-congresswoman-turned-Clinton-in-law Marjorie Margolies looks to retake her old seat, but faces strong challengers from across the party, in a race could set the tone for the Democrats in 2016. A win for the well-funded Margolies, whose son is married to Chelsea Clinton, could signal the strength of the Clinton machine. But Margolies has a checkered past: her ex-husband, former Iowa Congressman Ed Mezvinsky, was convicted on charges of fraud in 2001 and spent five years in prison. A recent report reveals that Margolies' charity, Women's Campaign International, spent an "unusually large proportion of its revenue on her own salary." The 13th District has been redrawn to include more working-class neighborhoods since Margolies was in office, and Boyle, who prides himself on a "100% pro-labor voting record," may have an edge with voters as the only candidate from inside Philadelphia city limits. Leach, the most liberal of the candidates, touts his advocacy for women's health and LGBT rights while Arkoosh, a practicing obstetric anesthesiologist, differentiates herself as the non-politician.

THE OUTLOOK

With no major Republican challengers emerging yet, the primary is the one to watch. Former Pennsylvania Democrats Executive Director Kevin Washo told ABC News this will be a "competitive" race, but that "she's not the only person in this race gaining traction. Could Margolies be the comeback kid, in a seat she famously lost after voting for Bill Clinton's budget?
