On Wednesday, state party Chairwoman Meredith Wood Smith of Portland and Democratic National Committee member Wayne Kinney of Bend announced their support for Obama.

That gives Obama a 6 to 2 lead in Oregon over Hillary Rodham Clinton, with four more Oregon superdelegates yet to declare.

Both Smith and Kinney said they are backing Obama because he won last week's Oregon primary and has demonstrated leadership the country needs.
