Key battleground state voter registration data shows influential shifts favoring GOP

The Democratic Party is losing its edge over the GOP in the critical swing state of Pennsylvania, with Democrats changing their party affiliation at more than twice the rate of Republicans, according to state data released after voter registration ended Monday evening.

A total of 9,088,583 registered voters were tallied across the state when the sign-up period ended at midnight on Monday. Registered Democrats maintained a lead over registered Republicans, at 3,971,607 registered Democrats to the GOP's 3,673,783. 

More than 1.4 million voters are registered as third-party or independent voters in the Keystone State. 

Though the Democratic Party accounts for nearly 44% of registered voters compared to the GOP's 40%, it has seen its advantage over Republicans dwindle this year.

In 2020, there were 9,090,962 registered voters across the parties in Pennsylvania, only slightly more than the 9,088,583 voters registered this cycle. 

President Biden won the state in 2020 by 1.17 percentage points​. That year, Democrats had a larger margin of registered voters compared to their Republican counterparts, at 4.2 million to 3.5 million. The data show that Democrats had a registration advantage over Republicans by 685,818 voters during an election Biden won by 80,555 votes.
