Democrats also scored significant wins in this year’s local elections in the Philadelphia suburbs, an area that is home to some of the most hotly contested voters in the country.

Democratic candidates won or maintained majorities in the councils of three Philadelphia-area "collar counties" earlier this month, a cautionary tale for the GOP’s chances in the nation’s suburbs.

Hershey is located in Dauphin County, which Trump lost to Clinton by just under 3 points in 2016.
