Kate Brown may be the incumbent in next year's Oregon gubernatorial race, but she's, in terms of overall fundraising, starting off, in a sense, in the underdog's role.

Brown has so far raised about $1.54 million, a shade less than the $1.68 million raised by likely November 2018 opponent Knute Buehler.

Brown, as of Tuesday, had also collected contributions from 2,405 donors during 2017. Buehler has nabbed money from 1,139 donors since August.

Experts such as Jim Moore, the director of the Tom McCall Center for Policy Innovation at Pacific University Oregon, believe the pair's battle could rival the $17 million or so collected by Democrat John Kitzhaber and Republican Chris Dudley in 2010.

Whereas Buehler's list of top 27 donors included 14 individuals, Brown's top 26 donors include 12 individuals, six political action groups and six businesses.

Three attorneys are among Brown's donors. Her best-known individual donor is television producer Dean Devlin, who made his name with such Portland productions as "Leverage" and "The Librarians." Devlin has so far given Brown $25,000, $50,000 less than her top donor.

In contrast, Buehler, a Republican state representative from Bend received $500,000 from Nike founder Phil Knight.

One thing that Brown might find positive: Buehler still hasn't generated the same name recognition as Dudley, a former NBA player who spent several seasons with the Trail Blazers.

"Dudley had a lot of out-of-state support because he was the NBA guy and got a lot of checks for a lot of money" from non-Oregon donors, Moore said. "Buehler likely won't get that because, well, he's not going to become nationally known for his stances on, say, health care."

Still, Brown is so far borrowing at least one page from Dudley: She counts six out-of-state donors among her top givers, compared to none for Buehler.
