Clinton wins Pennsylvania primary by a 12-delegate margin

The new delegates increased her margin of victory to 12 delegates, giving Clinton a total of 85 delegates in the primary, according to an analysis of election results by The Associated Press. Sen. Barack Obama won 73 delegates.

The final two delegates could not be awarded before Friday because there were incomplete results in two congressional districts. The Pennsylvania Department of State released results for all congressional districts Friday, with 100 percent of the precincts reporting. The results, however, are still unofficial.

They showed Clinton winning the primary with 54.6 percent of the vote, to 45.4 percent for Obama.

Clinton's campaign also announced a superdelegate endorsement Friday, by Jaime Gonzalez Jr., a member of the Democratic National Committee from Texas.

Both Clinton and Obama have picked up the pace of superdelegate endorsements since the Pennsylvania primary. Since then, Obama has added 15 superdelegates while Clinton has added 11, according to the AP tally.

Superdelegates are the party and elected officials who will automatically attend the national convention and can support whomever they choose, regardless of what happens in the primaries and caucuses.

Clinton leads in superdelegate endorsements, 269-248. But Obama has won more delegates in primaries and conventions, giving him the overall delegate lead.

The latest count: Obama, 1,736.5; Clinton, 1,605.5. It will take 2,025 delegates to claim the Democratic nomination at the party's national convention this summer.
