Del. Ken Plum, chairman of the House Democratic caucus, said Wednesday that Democrats are now actively searching for a candidate to run for the 94th House district following Del. Glenn Oder’s announcement that will resign.

Both parties’ have until Aug. 23 to field a candidate in the Republican-leaning Newport News area district for the November election.

Plum said Democrats hadn’t planned to run a candidate but now think they have a chance to win the seat because the incumbent — a well-liked moderate Republican who served nine years — is resigning Aug. 31.

The Fort Monroe Authority board unanimously voted Tuesday to appoint Oder as the next executive director.

He will succeed Bill Armbruster, who has served in the position since 2008, and is retiring in September after the historic fort is transferred to state control.

State officials want the 565-acre site to become a national park.
