It could be made by amending the state Election Code and passage by the House and Senate with Gov. Corbett's approval.
GOP leaders in both chambers say that they can pass it this fall. The governor this week said that he'd sign it.
This is a prime-time example of power politics by those in power.
After congressional reapportionment this year - done by the Republican-controlled Legislature - the state will have 20 electoral votes.
No large state has the system Pileggi proposes. States that do are Nebraska (38th in population with 1.8 million) and Maine (41st the population with 1.3 million).
California Republicans tried a similar move in 2007 but it failed in a Democratic-controlled legislature.
The change here could significantly impact national politics and the amount of attention Pennsylvania gets in next year's election.
Roughly half of what will be 18 congressional districts next year (a state's electoral vote total is equal to the number of congressional districts plus its two U.S. senators) cover rural Republican areas.
Odds, therefore, that the state extends its now five-cycle streak of delivering all its electoral votes to the Democratic candidate are longer than long.
In addition, the state would be politically devalued, no longer a top prize in national elections.
State Democratic Party Chairman Jim Burn says that the Pileggi move is another in a series of attempts to diminish the Democrats' one-million voter-registration edge.
He notes that the GOP also is pushing legislation requiring voter photo IDs, which he says can reduce turnout among poorer and elderly voters - especially in urban areas - who tend to vote Democratic.
That bill passed the House, 108-88, in June and awaits Senate action.
