The argument for Pennsylvanians

The Democratic primary voters in Pennsylvania can obviously vote for whichever candidate they prefer. But they should be aware that even if Clinton wins their state, she won't be able to surpass Obama in the overall popular vote or elected delegates. The only way Clinton can win is with the superdelegates. So Clinton's supporters in PA need to ask themselves, is that really how they want their candidate to win? Because if it isn't, they should vote for Obama, so Clinton drops out of the race and helps the party's democratically elected nominee win in November.
