Pennsylvania is one of only nine states that has a closed primary, which prevents the more than 1 million independent and non-affiliated voters from having a voice in choosing candidates in the primary election.
LWVPA opposes the current system of closed primaries which excludes participation by electors who do not register with one of the two major parties. LWVPA believes changing the primary structure to one which includes all electors would increase voter participation and could reduce political polarization.
LWVPA supports changing to an open primary system in which all electors, regardless of registration status, can participate in the primary of the major party of their choice or a semi-open system in which electors who are not registered with a major party can participate in one of the major party primaries. The same system should be used for both presidential and state/local primaries. (ref: LWVPA, Primaries, https://www.palwv.org/election-laws )
