Mitt Romney has added a win in Pennsylvania's Republican presidential primary to GOP victories in New York, Connecticut, Rhode Island and Delaware.
A total of five state primaries are being held Tuesday -- the fifth is in New York.
The five primaries are the first since Rick Santorum suspended his presidential campaign two weeks ago, essentially conceding the GOP nomination to Romney.
Pennsylvania is Santorum's home state.
Newt Gingrich had campaigned heavily in Delaware, hoping for a win there.
