HARRISBURG — A Republican leader in the Pennsylvania Legislature has renewed his politically charged effort to end the state’s winner-take-all method of allocating its Electoral College votes for U.S. president.

The prospects for approval are unclear, as the measure has been blasted by Democrats as vote-rigging, Republican Gov. Tom Corbett has not taken a position and the sponsor says the measure is not near the top of his list of priorities.

The bill introduced last week by Senate Majority Leader Dominic Pileggi, R-Delaware, made a change from a similar proposal that died in the last legislative session. Pileggi’s latest proposal would apportion 18 of the 20 votes based on the percentage of votes the candidates draw in the statewide popular vote. The other two votes would go to the overall winner.

In the last session, Pileggi sponsored a proposal that would have divided the votes according to who won the 18 congressional districts.
