We've got one hand on the remote and one on
our Delegate Calculator
as we try to suss out what different margins of victory mean for the two candidates. One thing, though, is certain: Hillary Clinton has already won 28 pledged delegates in Pennsylvania. The state has 158 pledged delegates in total, and it awards 55 proportionally by the statewide total and 103 proportionally by district. Since Clinton is projected to win the state's overall vote, she is guaranteed at least one more of those statewide-allocated delegates than Obama. Half of 55 is 27.5. Hence, the 28-delegate guarantee. Now we've got 130 left to divvy up.
