President Joe Biden may be getting a warning sign from Pennsylvania, where a growing number of voters are switching their party affiliation from Democrat to Republican.

The most up-to-date voter registration data from the Pennsylvania Department of State shows that 35,589 registered Democrats have switched to their party affiliation Republican this year, as of December 18, 2023. Comparably, 15,622 registered Republicans have switched their party affiliation to Democrat. There were also 20,908 former Democrats and 18,927 former Republicans who are now unaffiliated with either party.

The departure of voters and the net loss of 19,967 Democrats signals bad news for Biden, who only won Pennsylvania by some 80,000 votes in the 2020 election.

"Current voter registration trends and polling in Pennsylvania should be setting off alarms for President Biden and Democrats at the state and national level, with pocketbook issues remaining the top concern of voters who overwhelmingly feel that things are headed in the wrong direction," Erik Telford, a senior vice president of public affairs at the Commonwealth Foundation, told Newsweek.
