PORTLAND, Oregon - Barack Obama on Tuesday won the Democratic presidential primary in the northwestern state of Oregon, US media said.

The Illinois senator was projected to win the state, which has 52 delegates at stake, NBC, CNN and Fox said.

Earlier, Obama's rival Hillary Clinton won a decisive victory in the southeastern state of Kentucky, which has 51 delegates at stake.

Television projections gave Obama a victory in Oregon. With 11 percent of precincts reporting, he led Clinton by nearly 40,000 votes.

In his speech, Obama was fulsome in his praise of his indefatigable Democratic rival.

"Senator Clinton has shattered myths and broken barriers and changed the America in which my daughters and yours will come of age," he said.

But Obama hammered McCain, in the latest spat of a fierce foreign policy row.

"The Bush policy that asks everything of our troops and nothing of Iraqi politicians is John McCain's policy too. So is the fear of tough and aggressive diplomacy that has left this country more isolated and less secure than at any time in recent history."

President George W. Bush last week implicitly accused Obama of wanting to appease dictators, with his offer to speak to some of America's most sworn foes -- and McCain launched his own fierce attack on the same lines.

In a new sign of his growing political might, Obama's campaign said he had raised 31 million dollars in April.

Clinton's communications chief Howard Wolfson said her campaign raised 22 million dollars in the same month.

Both Obama and Clinton were heading to Florida Wednesday. The Sunshine State's primary results, like Michigan's, were voided by Democratic bosses over a scheduling row.

Clinton however claims she has won the popular vote, if Michigan and Florida are counted, and argues she would therefore be the strongest nominee.

The last contests in the race are in Puerto Rico, Montana and South Dakota.
