How Pennsylvania's Primary Works

Pennsylvania uses a Closed Primary system

⚖
Closed Primary
Only voters registered with a political party can vote in that party's primary election. Independent and unaffiliated voters are excluded.
How It Works
Voters must register with a party, often weeks or months before the election, to participate. If you're registered as independent or unaffiliated, you cannot vote in either major party's primary.
IVP's Position
Closed primaries lock millions of independent voters out of the elections that matter most. In many districts, the primary is the only competitive election.
