Pennsylvania

It lost a pretty red area - the Cranberry Twp part of Butler county - and gained more of Democratic Allegheny county. Beaver County itself is a red county, but despite the entire county being part of the district, it's dwarfed by the part of Allegheny county part of the district. Imo, CD17 actually got more Democratic, not less during redistricting.

Both candidates are from Allegheny county, DeLuzio - Aspinwall/Fox Chapel area, Schaffer - Ross Twp area.

I've seen more ads from DeLuzio, but Rs are running their usual stuff trying to link Ds with the more well-known progressive Dems. I find those ads juvenile and inane, but I guess Rs think they work. Seen bio type ads from both candidates.

Here's an interesting side note, where I live is a quite conservative and red area with outnumbered and discouraged Dems. But the other day got a letter in the mail from my township's Dems telling me they were holding an event next weekend to gather and meet the candidates including DeLuzio and the local state house candidate! Usually mailers come from the county Dem party making the letter a first! It says something that Dems even in a red township like mine are organizing and intent on getting out every Dem voter.
