Obama concedes
In Indiana, campaigning for its May 6 election, Obama offered his congratulations to Clinton.
"She ran a terrific race," Obama said."And, I want to thank the hundreds of thousands of Pennsylvanians who stood with me today. There were a lot of folks who thought we wouldn't make a race of it and would be blown out. We closed the gap.
"We registered a record number of voters. And it is those new voters who will lead our party to victory in November."
Obama then returned to his campaign theme of running a campaign to bring change to the country.
