Governor John Kitzhaber announced he will call for a special election as soon as he receives Congressman David Wu's official resignation.... and he'll give the Secretary of State plenty of time to hold a primary election. Democratic party of Oregon Executive Director Trent Lutz says he's heard of several potential candidates. State Labor Commissioner Brad Avakian and State Representative Brad Witt,  both Democrats, have already announced plans to run for the seat.  Wu's Republican opponent in the last election, Rob Cornilles is expected to run. And Washington County businessman Rob Miller is considering his options.
