Here's a look at the contested races on the ballot in Chester County:

U.S. Senate

Two-term Democratic incumbent Bob Casey Jr., 57, is unopposed for the Democratic nomination. He'll face the winner of the Republican race pitting U.S. Rep. Lou Barletta of Hazleton against state Rep. Jim Christiana of Beaver County.

Pennsylvania Governor

Incumbent Tom Wolf is unopposed for the Democratic nomination. Vying for the Republican nomination are state Sen. Scott Wagner of York County, retired businessman and U.S. Army veteran Paul Mango of Pittsburgh and attorney Laura Ellsworth of Pittsburgh.

Pennsylvania Lieutenant Governor

Incumbent Mike Stack faces a plethora of Democratic challengers, including Braddock Mayor John Fetterman, Chester County Commissioner Kathi Cozzone, Montgomery County Commissioner Ray Sosa and Nina Ahmad, a former aide to Philadelphia Mayor Jim Kenney.

Republicans seeking the nomination are Washington County Commissioner Diane Irey Vaughan, management consultant and Bellevue councilwoman Kathy Coder, Montgomery County Commissioner Joe Gale, Montgomery County developer Jeff Bartos and pro-life advocate Peg Luksik.

U.S. Representative 6th District

The 6th District, formerly the second most gerrymandered district behind the old 7th - was radically redrawn, and now includes most of Chester County, along with the city of Reading. The addition of liberal stronghold Reading is great news for Democrats. Ryan Costello, a very moderate Republican incumbent, will not seek re-election. Former federal prosecutor Greg McCauley is running in his place. Costello said his decision was partially motivated by the redrawn PA congressional map which he saw as unconstitutional, and partially due to being stuck between extremists in his own party and extreme progressives, and being unable to make anyone happy. He had criticized Trump extensively, but has been at the center of numerous scandals flamed by area progressives, including issues revolving around town halls and his votes supporting certain Trump measures like the tax bill (he was against other Trump stances, like climate change and healthcare).

>>Rep. Costello Will Not Run For Re-Election

Chrissy Houlahan, a businesswoman, is the Democratic candidate and now, given the redrawn district, a heavy favorite. The 6th has been red for more than a decade.
