The top Republican in the state Senate is calling for movement on his bill which would affect primary elections in the Commonwealth. When Pennsylvanians go to the polls on Tuesday, only those registered Republican or Democrat will be able to vote. That would change under a bill sponsored by Senate President Pro Tem Joe Scarnati, which would open up the primaries to those registered Independent. Scarnati says that would represent a greater percentage of the voting population. The measure is currently before the Senate State Government Committee.
