The May 15 primary coming up in Pennsylvania's 7th district is going to be very interesting
Emily's List is endorsing Susan Wild, and the Our Revolution is endorsing Greg Edwards.
What makes the 7th district interesting is that this district was involved in the redrawing of the Pennsylvania congressional map:
"Following a court-ordered redrawing of the Pennsylvania congressional map in February 2018, the new 7th district was made up of parts of Charlie Dent's (R) old 15th district (71.6 percent), Matt Cartwright's (D) old 17th district (24.8 percent), and Tom Marino's (R) old 10th district (3.6 percent). It was based around Allentown, Pennsylvania.
The new 7th district voted for Hillary Clinton over Donald Trump in the 2016 presidential election by a 48.7 percent to 47.6 percent margin.[1]
The Democratic primary features a matchup between Greg Edwards, John Morganelli, and Susan Wild. The leading candidates are divided ideologically as Edwards and Wild lean toward the progressive and mainline wings of the Democratic Party, respectively, while Morganelli is to the right of most Democrats on issues like immigration and abortion."

Because of this redrawing Democrats have a very good chance of winning
