This blog is going to begin a series of posts based polling data collected during the 2016 Oregon General Election. We will present the most prominent and interesting polling numbers first. Less prominent contests will come later – many in 2017.
We believe these analyses to be accurate. Though the headlines this year emphasize the inaccuracy of polling, our polls, just as in 2014, the firm’s polling correctly called every 2016 Oregon statewide partisan and measure contest. Although not a foolproof measure of accuracy, it is best assurance we can offer.

Oregonians outside the more urban Tri-County area voted to support expanding prohibition. As noted in the last post, the national pattern where urban areas were more supportive and rural areas were less supportive of prohibition also held in Oregon.

Oregonians had passed a Prohibition Constitutional Amendment in 1914. The 18th Amendment to the United States Constitution only took effect in 1920. In 1916, Oregonians were asked whether they wanted to pull back from prohibition (Measure 8) or to expand the impact of prohibition (measure 9).
The rejected pulling back by a landslide. The only place it was close was in Multnomah county. Across the nation prohibition did better in rural areas and worse in urban areas. That was true in Oregon as well.
