you guys really think this county will trend 12-17 points just because Biden's from there? Look what happened to Gore in his home state, Romney in MA, Trump in NY, Clinton in Arkansas, etc. Biden's a better fit than most Democrats but a swing like that seems unrealistic. I would be curious if he gets a small bump in the counties throughout the region though.
no one said that, it’s not unreasonable to predict a double-digit swing if biden approaches double digits in the NPV and appeals better to WWC voters by virtue of not being hillary (which is demonstrated in all polls and all subsequent PA elections from 2016). any “home effect” is just the cherry on top
