Democrats hold a significant voter registration edge in Pennsylvania, but Republicans have been steadily eating into it this year.

After the September 5th report showed some stabilization for Democrats, the new September 26th report has the margin between the two parties almost back down to the levels of the August 1st report.

There are 4,116,095 Democrats and 3,200,191 Republicans registered in the commonwealth of Pennsylvania. That’s a gap of 915,904.

Additionally, there are 694,341 voters of no party and 448,202 members of minor parties. Altogether that makes for 8,458,829 registered voters in the state.

Republicans made gains in 57 of PA’s 67 counties. Once again, their biggest gains came in the Southwest where Appalachian residents are fleeing the Democratic Party. Among the standouts where Republicans reduced the margin between the GOP and the Dems were: Westmoreland (984), Butler (459), Cambria (450), Fayette (439) and Washington (429).

It’s also worth pointing out that Republicans are making up ground in Luzerne County (382) and running up the score in York County (944).  

Democrats are still able, however, to pad their margins in Philadelphia (4,527) and Allegheny (1,744) Counties.

The SEPA Counties of Delaware (743) and Montgomery (615) are also still trending blue.

As I’ve noted in the past, though, the most intriguing trends have been in the two other SEPA Counties: Bucks and Chester. Republicans were able to regain ground in Bucks (463) and get the Dems’ registration advantage to under 10,000. Meanwhile Chester, which is the only collar county where the GOP holds the edge, continues to go against the grain. The Dems were able to shave 215 off the Republican margin there.

Expect one more report as we approach the October 11th deadline.
