DHM Research in Portland surveyed 536 Oregonians online July 22-27 about their opinions on the primary candidates.
Republican respondents to the poll were asked which GOP candidate they preferred to receive the party nomination. Eighteen percent surveyed supported Trump, followed by 12 percent for Wisconsin Gov. Scott Walker, 11 percent for former Florida Gov. Jeb Bush, and 10 percent for Texas Sen. Ted Cruz.
Clinton, who visited Oregon this week for a fundraising event, leads the other Democratic candidates with 44 percent support among Democratic voters. But Oregonians in the party also gave strong support to Vermont Sen. Bernie Sanders, at 39 percent. The Democrat-only sample had a 6.9 percent margin of error.
The former Secretary of State polled much stronger than Sanders among female Democrat respondents and older voters.
Sanders was particularly popular among young voters. Nearly 60 percent of 18- to 29-year-old Democrat respondents said they support the Vermont senator for their party’s nomination.
Sanders will be in Portland Sunday night at the Moda Center for a campaign rally.
The overall poll results had a margin of error of 4.2 percent.
