In recent years with the candidacy and election of Donald Trump, he has made a lot of the more rural counties much redder, although it’s hard to say how long that will last now that Trump is no longer a (likely) candidate going forward. While there has been a shift back towards the blue column in 2020, Trump changed the map over the past two elections in many less populated counties.

New York State is decidedly more blue than Pennsylvania, even in its more rural outlying counties.

New England, especially Vermont and Massachusetts are quite blue, especially after the most recent elections.
