On October 17, the Pennsylvania House State Government Committee passed two similar bills that let independents vote in primaries. HB 976 only applies to independent voters; HB 979 applies to independent voters and also registered members of parties that don’t have their own primaries.
Both bills were supported by all Democrats on the committee. All Republicans on the committee voted against the bills.
I would have voted against it too.
Parties should be in charge of their own nomination process.
