A quiet spring brings encouraging seeds for Pennsylvania’s Democratic Party.

As the first months of the Biden Administration unfolded, and COVID cases steadily declined, PA Dems recovered from their post-election slump. 

Back in February, the party held a statewide advantage of 624,315. As of June 14, however, that margin has improved to 630,075. Total registrants are down, so counties are still culling their rolls, although now this is tending to hurt the GOP instead. 

At the moment, Pennsylvania has 4,057,723 Democrats and 3,427,648 Republicans. For comparison, four months ago it was 4,074,825 Democrats and 3,450,510 Republicans

To examine what we can discern from these changes, let’s dig into the numbers.

A quick note: I explore our changing voter trends by tracking the gains one party accumulated in registrations over the other party. For example, R+500 means that the Republican Party gained a net 500 more registered voters in that county than the Democratic Party did over this time period, while D+500 indicates the opposite.

Blair: D+50
Centre: D+81
Clearfield: R+284
Columbia: R+105
Huntingdon: R+86
Juniata: D+7
Mifflin: R+22
Montour: R+12
Northumberland: R+169
Snyder: D+144
Union: D+6

Right away we can see what makes this particular update unique. With several rural counties culling their rolls after November, disproportionate Republican losses means unexpected Democratic gains. Normally Centre County, home to Penn State, would be the only spot here where we’d expect to see blue.

North Central:
Bradford: R+46
Cameron: R+9
Clinton: R+99
Elk: R+161
Lycoming: R+163
McKean: R+75
Potter: R+50
Sullivan: D+2
Tioga: R+99

This area was one of the few silver linings for Democrats in February, so it’s only appropriate that it serve that role for the GOP now. That minimal gain in Sullivan is the only sign that anything is out of the ordinary. 

Carbon: R+711
Lackawanna: R+143
Luzerne: R+403
Monroe: D+127
Pike: R+188
Schuylkill: R+252
Susquehanna: R+61
Wayne: R+114
Wyoming: R+12

NEPA is one place Democrats should be disappointed. The long-term exodus of support from Lackawanna and Luzerne counties continues practically unabated, despite the Presidential ascension of Scranton’s native son. Their strength in Monroe County (thanks to the tourist-friendly Pocono Mountains) is a welcome but insufficient substitute.  

Clarion: R+44
Crawford: R+239
Erie: D+103
Forest: R+19
Jefferson: D+66
Mercer: R+182
Venango: D+4
Warren: D+326

Once again you can see unusual results in rural counties such as Jefferson, Venango and Warren counties. The most noteworthy development, though, is in Erie. Back in February, the lakeside county had just undergone a post-election purge that saw the Dems lose over 5,000 voters from their margin. While this new gain may be comparatively small, every vote matters in this Trump-Biden county.  

South Central:
Adams: D+111
Bedford: R+105
Cumberland: D+2
Dauphin: D+634
Franklin: R+90
Fulton: R+49
Lancaster: D+461
Lebanon: R+103
Perry: D+92
York: D+440

This is a tricky region for Democrats, as these numbers contain both ‘fool’s gold’ and legitimate positive trends. Cumberland and Lancaster, for instance, are some of the party’s most promising long-term opportunities. Adams and York, meanwhile, are likely the result of the aforementioned post-election re-shuffling.  

Berks: R+345
Bucks: R+1,164
Chester: D+853
Delaware: D+2,538
Lehigh: D+343
Montgomery: D+1,981
Northampton: R+184
Philadelphia: D+7,748

The one major outlier that catches the eye is the bright red in Bucks County. Since Bucks County didn’t trim its voting rolls until after my last update, they look out of place on this map. The rest of these numbers, though, are quite encouraging for the Dems, given that Biden’s growth in the collar counties around Philly was pivotal to both his victory in 2020 and his hopes for 2024.

Allegheny: D+311
Armstrong: R+259
Beaver: R+476
Butler: R+309
Cambria: R+425
Fayette: R+432
Greene: R+319
Indiana: R+562
Lawrence: R+358
Somerset: R+152
Washington: R+933
Westmoreland: R+809

It’s the same story every time. As the Southeast gets more and more Democratic, the Southwest gets even more Republican. I’ve spilled quite a bit of digital ink over the erosion of ancestral Appalachian Democrats, and the trend shows no sign of abating anytime soon. All the while, Allegheny remains a blue island amidst the red sea.


I’ve been tracking Pennsylvania’s voter registration trends for five years now (wow, how time flies). So I’ve gotten to know what a general registration update tends to look like. Typically these reports show Republican gains everywhere except the Southeastern suburban counties.  

After all, this is a commonwealth full of ancestral Democrats who have either recently left the party or likely soon will. Take the D+630,075 statewide margin I mentioned above, back in October 2016 it was D+913,017. 

Every now and then, however, a more substantive trend becomes clear. In retrospect, GOP growth in 2016 was a harbinger of the Trump upset. The Democratic resurgence in 2018 forecast their midterm suburban triumph, and the consistent Republican gains of the summer and fall of 2020 suggested a closer race than the polls indicated.

Thus far, 2021 has been dominated by the post-2020 sifting of the rolls. For now we can’t decipher what the 2022 landscape will look like, but if change is on the horizon, we’re likely to see it in the voter registration numbers first.

Yet, at this moment, I’m tempted to predict that the 2022 cycle will mainly be a continuation of 2020. Although, since such an occurrence would be a historical anomaly, I’ll stick to the numbers for now.
