Trump will win with more than 60-70% now that Cruz and Kasich are out of the race.
Oregon is a vote by mail state. The last day counties had before they were required to mail the ballots out was May 3, when Trump won Indiana. Cruz dropped out that day. Kay-sick the next. Some counties likely sent out the ballots before that day. It's possible there were some ballots returned prior to Cruz and Kasich dropping out. That may erode into Trump's margin a bit.
