Without waiting for tomorrow's official primary results, eyes already are turning to the general-election rematch between Snohomish County Council Republican incumbent Jeff Sax and Democratic challenger Dave Somers.

Toss in an independent candidate, Greg Stephens, and it's more of a wrestling match than a heavyweight boxing bout for the District 5 seat.

For Somers, who defeated fellow Democrat Steve Hobbs in the primary, it's a chance to avenge his loss to Sax four years ago, when Somers was the County Council chairman.

For Sax, it's an opportunity to reverse historical trends not in his favor. In the past 12 years, no one has won re-election in District 5, which includes Maltby, Monroe and Sultan.

Republicans risk losing their council majority if Sax fails, and Democrats relish the chance to take back control.

"You can count on this one being interesting," said County Councilman Kirke Sievers, a Democrat not up for re-election this year.

Though Sax isn't the only Republican running for re-election, many agree District 5 is the most likely district to swing. Sax, known for his pro-development stance, has angered some constituents who say more balance is needed at the county level.

Stephens is pushing for the incorporation of Maltby. He also supports the construction of the Brightwater sewage plant, a project that Sax has fought since joining the council.

Two other County Council incumbents — Republican John Koster and Democrat Dave Gossett — also are running for re-election. Koster faces former Marysville Councilwoman

Suzanne Smith, a Democrat, in District 1, and Gossett is being challenged by Republican Eva Davies for the District 4 seat.

Somers, who was known for liberal positions while on the council, has been painting a picture of moderation this time around. He's also the benefactor of having Sax's record — more recent than his own — to challenge.

Understanding that momentum is the key to the race, however, Sax's supporters already have sent out a mailer extolling his virtues. Sax also is about to propose an increase in traffic-mitigation fees tied to development, taking some of the punch from one of Somers' biggest platform issues.

Though Sax says the measure isn't political — discussions over the 10-year comprehensive plan update begin next week — it shouldn't hurt his re-election bid.

"I think [such a proposal] will fly. I think I'll support it," Koster said, adding it would be hard for Democrats on board not to consider increasing mitigation fees.

The only thing Sax and Somers might agree on is what the issues are. Where they stand on transportation, public safety and the environment are the differences.
