If you’re watching the state political landscape and in particular the 35th Legislative District, you might have long ago stopped looking at the Senate race to focus on the campaigns being waged by two Republicans for the opportunity to unseat a Democratic incumbent.

You might be assuming that Tim Sheldon will again open an unlocked door to another term as a state Senator. The primary, though, could be interesting. And Sheldon has made some critics out of people who once were his backers, primarily people in Belfair, because of his work as a county commissioner.

Sheldon, as most of you know, is a Democrat, albeit (How should we put this?) an atypical one. For years his votes on most controversial issues have been aligned with the Republicans. The Democrats enjoyed their majority status in the chamber with his insistence on remaining a Democrat and have been safe from his maverick ways as long as the margin never got close. Once Democrats outnumbered Republicans by just three in the Senate, though, the GOP leadership was able to poach away control by nabbing Sheldon and Rodney Tom, the Democrat who once was Republican and is now the figurehead for the Senate Majority Coalition.

In Mason County, which is the bulk of the 35th, Sheldon has held strong. In 2010 he received 57 percent of the vote against Nancy (grandma) Williams, though that big margin might be deceiving, because she didn’t wage much of a campaign.

The election of 2006 might be a more telling picture. That year, one in which voters had to pick a party, Sheldon only received 43.1 percent in the primary against two challengers. One was a Democrat from the Howard Dean wing. The other was a Republican. In fact, the Democrat, Kyle Taylor Lucas, accused by many of moving into the district just to run against Sheldon, came in second place, netting 32.5 percent of the primary vote. Had she run in 2010 or this year and seen the same result, she would have been on the General Election ballot because of the state’s Top Two primary system.

So far Sheldon faces two opponents in the primary this year. Travis Couture, the Republican, describes himself on his website as “a conservative libertarian.” His arguments espousing that philosophy is clear on the website, and he delivers a message that might well resonate with the 35th District’s more conservative voters. So might his Facebook criticism of Sheldon, “Next time you see an illegal immigrant going to college on your taxpayer dime, just thank Tim Sheldon for voting to pass that this year in the Senate.”

The Democrats have Irene Bowling so far. She has run a music instruction business in Kitsap County and has been well known locally. During the selection process for the county commissioner position left open by Josh Brown, Bowling proved herself a competent candidate. She answered questions well and swayed enough precinct committee officers to make her the second choice as Brown’s successor. I have little doubt that the vast majority of people who voted for Taylor Lucas in 2006 will side with Bowling this time around in the primary. If she gets more than the 32.5 percent Taylor Lucas got, she could even emerge as the 35th District’s first choice out of the primary.

If that were to pan out, then the question becomes whether Couture can cut enough into Sheldon’s lead to do the unthinkable, putting Sheldon into third place.

One of Couture’s challenges could be raising money for the race, at least from the state party. Party organizations get to donate in big amounts. Sheldon isn’t going to get money from either party, but he already has almost $80,000. Sheldon has in the past, though, prevented Republican candidates from getting GOP party money to run against him, or so I’m told. It’s as if every dollar he gets has a huge multiplier effect. It’s early in the game, but that could be tough for Couture. If he as a first-time candidate proves especially adept at raising money and getting signs on voters’ lawns, he could make it interesting. Where Couture might make his biggest splash is on social media, which doesn’t cost a lot and can have a big connector factor.

If there is enough anti-Sheldon sentiment out there then this race could be highly entertaining. In the 2012 Mason County Commissioner primary race Sheldon received 29.4 percent of the vote as an incumbent, a half point ahead of the second-place candidate, Democrat Roslynne Reed. Sheldon won by 8 percentage points in the general election, but those 2012 numbers demonstrate he is not invincible. He does not enjoy the kind of support Norm Dicks had in the Sixth Congressional District.

If you were betting money on the 35th District race, I still wouldn’t dissuade you from betting on Sheldon. But you might look at 2012 and have reason to question your certainty. If he makes it to the general election I don’t see him losing that one. The best chance to unseat him is likely the primary. Bowling, assuming she is the only Democrat who runs, will get the votes from those leaning left. The question will be how the conservative votes will split, whether Couture can effectively make the case that he is more their representative than the incumbent.
