OLYMPIA — Gov. Chris Gregoire said Monday a special election to replace Democratic U.S. Rep. Jay Inslee will be held in the old boundaries of the 1st Congressional District and it may cost taxpayers as much as $770,000 to conduct.

The special election will be held in conjunction with this year’s regularly scheduled primary and general elections. The top two vote-getters in August would advance to the November ballot with the winner able to take office in December when results are certified.

Inslee resigned last month to run full time for governor this fall. He will likely face state Attorney General Republican Rob McKenna, who is a Republican. Gregoire said state law and the Constitution require she call an election even though the winner will serve less than a month.

The past several days she’s been trying to figure out if she could conduct it in the new boundaries drawn up through redistricting rather than the old ones. But it became clear the U.S. House would not seat the winner of a special election unless they won in the same district that Inslee served.

“I am concerned about the voter confusion that could result,” Gregoire said in a statement. “This is an unusual situation where an election to fill a vacancy occurs in a year of redistricting. The result is some voters will cast a ballot in the current 1st District for the special vacancy election and will also cast a vote in their new district for their next representative in Congress.

“I’ve asked the Secretary of State to work with county election officers to pursue an aggressive voter education campaign so constituents understand the votes they are casting. I also ask the media to help educate and inform the public in the existing and new 1st Congressional Districts,” she said.

Secretary of State Sam Reed estimated the state will spend as much as $770,000 to reimburse Snohomish, King and Kitsap counties for their costs in conducting the election in the old district boundaries.
