Democrat Jonathan Kreiss-Tomkins has won Alaska’s open governor’s race, defeating three Republicans and returning the state’s highest office to Democratic hands for the first time in more than two decades.

Kreiss-Tomkins, a 37-year-old former state lawmaker, will succeed Republican Gov. Mike Dunleavy, who was barred by term limits from seeking another term. He will also become the youngest governor in Alaska’s history.

His victory came in a four-way, all-party contest that attracted millions of dollars from national political groups. The race drew particular attention as Republicans sought to retain the office and Democrats saw an opportunity to compete for a seat that had been held by the GOP.

The Republican vote was divided among three candidates. President Donald Trump endorsed Bernadette Wilson, but his backing did not narrow the GOP field. That split helped Kreiss-Tomkins prevail in the contest for the open seat.

The result marks a generational shift as well as a change in party control. A millennial and former legislator, Kreiss-Tomkins will take office as Alaska’s youngest governor, succeeding a Republican governor unable to run again.

For Democrats, the victory ends a long wait to win the state’s governorship. Alaskans had not elected a Democrat to the corner office in more than 20 years.
