In addition to being one of the closest governor’s races in recent memory, the fight between Gov. Kate Brown and Rep. Knute Buehler is the most expensive.

In 2018, Brown as of Wednesday has raised $7,805,941, according to Oregon Secretary of State’s Office records.

Buehler has raised $8,115,084 this year, $1 million coming from Nike co-founder Phil Knight in what was the largest contribution in state history. In September, he got $750,000 from the Republican Governors Association.

Both candidates came into the race with million-dollar war chests, and collectively have raised $20.2 million as of Thursday . . .
