I can only imagine the outrage that this plan will provoke. Wisconsin level outrage, perhaps. What are some synonyms for "evil"?

Such an act in PA and other states might spur adoption of the National Popular Vote Compact in other states to get closer to the 270 mark where the presidential election is decided by the popular vote. I doubt it would happen in time for the 2012 election, though. If Obama did lose the election due to strange electoral vote splitting in PA and MI even though he got 52% of the vote or so, then I think there would be a lot more motivated support behind eliminating the electoral college. I think this kind of plan that the GOP in PA is cooking up could only work once.
I think it would be better for all states to have the same process for assigning their electoral votes. Awarding EVs by district would be a good method in all the states if so many of these things weren't Gerrymandered. Going by popular vote may well be the best method, though an even better method would be to allow runoff voting and enfore a majority needed rule for electing the president.
