The District 30 race for state Senate between incumbent Democrat Tracey Eide and Republican challenger Tony Moore is too close to call.

The first results Tuesday night showed Eide ahead of Moore by about 350 votes (10,393 to 10,041). As of Wednesday, that margin increased to 477 (11,512 to 11,035).

In the August primary, Eide received 11,045 votes to Moore’s 10,682 votes — a margin of 363 votes.

Eide was first elected to the state Senate in 1998, and is the Democratic majority floor leader. Moore is a small business owner and current president of the Federal Way School Board.

A victory for Moore in this hotly-contested race would put Republicans closer to taking control of the state Senate depending on the outcome of several close contests around the state. In terms of finances, the Public Disclosure Commission indicates that Eide raised $242,350.99 and spent $210,000.78. Moore raised $158,590.40 and spent $154,886.05.

On Tuesday, Eide was not surprised by the close margin of votes, but remained confident that her lead would hold.

“(The 30th District) knows me well enough and what I’ve accomplished,” she said, noting high-profile issues such as the intermediate driver’s license program and cell phone law for drivers.

Moore said the close contest confirms the balanced and independent nature of District 30 voters.

“It’s good to be in a community that’s so balanced,” he said Tuesday night, confident the race will turn out in his favor. “We’re hoping to close the gap and pass it. It’s a wait-and-see game.”
