After Barack Obama secured the delegates needed for his party's presidential nomination,  Sen. Ron Wyden became Oregon's last Democratic superdelegate to announce his endorsement.  Andrew Theen reports.

Wyden sat on the fence for a long time.

Tuesday night, as Montana and South Dakota finished voting, he was among three uncommitted superdelegates from Oregon.

Two of those -- Oregon Secretary of State Bill Bradbury and state Democratic party vice chair Frank Dixon -- endorsed Obama when the polls closed.

Wyden waited until Wednesday morning to announce that he, too, would back Obama.

Wyden has expressed disdain for the superdelegate process.  He said throughout the primary process he would remain neutral until the end, and that he would happily  work with either candidate.

He said in a release that grassroots voters, not superdelegates, ultimately nominated Obama.

Governor Ted Kulongoski and Congresswoman Darlene Hooley were the two superdelegates from Oregon who supported New York Senator Hillary Clinton.
