The Pennsylvania primary for president and all other office is scheduled for April 23. Although many legislators want an earlier presidential primary, SB 224, the bill to move the primaries for 2024 to March, has not made any headway. The legislature is not in session but returns in late September. When it returns, it will be concentrating on the budget. Most observers do not expect SB 224 to pass.
That would be interesting if Pennsylvania held their primary first.
