Incumbent Rep. Cathy McMorris Rodgers and Democratic candidate Lisa Brown are going head-to-head in the race for Washington's congressional fifth district.

A Senate race is also taking place in Washington state, along with a gubernatorial race to replace current Idaho Gov. Butch Otter.

Below is a look at some of the races and initiatives Washington and Idaho voters will see on the ballot this year.

McMorris Rodgers took the remaining seven counties – Columbia, Pend Oreille, Ferry, Walla Walla, Garfield, Asotin and Stevens counties.

SPOKANE COUNTY SHERIFF RACE:

Incumbent Spokane County Sheriff Ozzie Knezovich is expected to easily win the race. His only challenger is Scott Maclay, who legally changed his name to Dumpozzie Dot Com.

Maclay pulled 13 percent of the votes in the primarily race with nearly 8,900 votes. In early September, Maclay was killed in a motorcycle crash near St. Maries, Idaho.

Spokane County Elections Auditor Vicki Dalton said the name “Dumpozzie Dot Com” will remain on the Nov. election ballot and his votes will still be tallied. According to law, if a deceased candidate wins the election, the affiliated party will select three candidates to send to the Board of County Commissioners. The commissioners will then decide the winning candidate of the three.

SPOKANE COUNTY COMMISSIONER RACE, DISTRICT 3:

Democrat Robbi Katherine Anthony is challenging Republican incumbent Al French for the Spokane County Commissioner position. French received 44 percent of the votes in the primary compared to Anthony’s 54 percent.

SENATE RACE: CANTWELL VS. HUTCHISON

During the primary, 28 candidates challenged Washington state incumbent Sen. Maria Cantwell, a Democrat seeking her fourth term.

Republican Susan Hutchison is now challenging Cantwell in the race for Senate during the general election. Hutchison is the former Washington State GOP Chairman. She stepped down as chair earlier this year but did not file her candidacy for U.S. Senate until just before the deadline in May.

She said the Seattle City Council’s vote on the repealed head tax was her tipping point.

At a recent debate, Cantwell and Hutchison discussed immigration and border security, Trump administration tax cuts, health care, gun policy and troops in Afghanistan.
