Pennsylvania voters are probably not going to find out tomorrow which candidate won the most delegates to the Democratic party's national convention.
As in other Democratic contests, Pennsylvania awards delegates based on the statewide vote and the vote in individual congressional districts.
But unlike most states, Pennsylvania has a large number of counties split into multiple congressional districts. That could delay results by a day or more as election officials work to assign votes to the appropriate districts.
Fifty-five will be awarded based on the statewide vote, which should be available tomorrow night. Another 103 delegates will be awarded based on the vote in individual congressional districts.
All delegates will be awarded proportionally, as they are in every Democratic contest.
