Washington (AP) Democratic Party Chairman Howard Dean says that either Hillary Rodham Clinton or Barack Obama must drop out of the presidential race in June in order to unify the party and win the election in November.

But Dean didn't say which candidate should drop out, only that it should happen after the voters had their say in the primaries, which end June 3rd.

In an interview on ABC's “Good Morning America,” Dean also said that while the party rules say some democratic delegates can wait until the party's august convention to make up their minds, that would be too late to unify the party.
