Democrat Conor Lamb’s victory over Republican Rick Saccone in last month’s special congressional election was seen as a positive sign for Democrats.

But it’s also a sign that in many working-class pockets of Pennsylvania, unions still hold considerable sway.

Rick Bloomingdale, president of Pennsylvania’s chapter of the AFL-CIO, said the group is working with local unions to focus on a handful of races heading into this year’s midterm elections.

Lamb’s new race for the 17th Congressional District under the redrawn map is at the top of the pile.

A Republican Pennsylvania congressman has announced that he will not seek re-election, boosting Democratic hopes of winning his House seat.

U.S. Rep. Ryan Costello announced on Sunday that he would not be running, ending weeks of speculation about his future.

During an appearance on MSNBC, the second-term congressman called it "the most difficult decision" he's ever had to make and said it was due to a number of factors including the state's new congressional map.
