Politics of Oregon

Like many other U.S. states, the politics of Oregon largely concerns regional issues.Oregon leans Democratic as a state, with both U.S. Senators from the Democratic party, as well as four out of Oregon's five U.S. Representatives. The state has voted Democratic, by relatively small margins, since 1988 in presidential elections. Both houses of Oregon's legislative assembly have been under Democratic control since the 2012 elections.

The state is broken up into two main geographically separate political areas: the liberal cities of the Willamette Valley and the rest of the state, whose voters are moving from conservative to libertarian. While about 47% of the population of Oregon lives in the Portland metropolitan area as of 2013, the state has a rural population with generally conservative views on same-sex marriage and state taxes. On most other issues, however, the state leans considerably left, including on public health care,medical marijuana,assisted dying and environmental protections.

For the first half of the 20th century, Oregon was the most consistently Republican west coast state. In 1954, the upset of incumbent Republican Senator Guy Cordon by Democrat Richard L. Neuberger, along with Democratic wins in the U.S. House and statewide races and pickups of fourteen and two seats in the state House and Senate, respectively, signaled the beginning of a shift towards the Democratic Party. The last Republican governor of Oregon was Victor G. Atiyeh, who served from 1979–1987. Since 1988, Oregon voters have consistently favored Democratic candidates for most major elected positions, including the U.S. presidency.
