That's interesting, Meredith, but I also think that Portland-area voters are a little frustrated with the progressive movement, particularly in the wake of the debacle with decriminalizing drugs that the legislature recently rolled back. There may be some local dynamics that really matter in Oregon, but aren't as influential elsewhere in the country, that are holding progressive candidates back — as you can see in my previous post about polling in the area regarding homelessness and crime. Both the 5th and 3rd districts are in the Portland area, so progressives there may be suffering some blowback from these issues.

That's a good question, Nathaniel. It could be that big spending wins primaries. Another takeaway could be that progressive candidates are losing steam. In the 3rd and the 5th, the candidates more aligned with the progressive wing ended up losing (Jayapal and McLeod-Skinner). But I don't think that's the take away. I think it's more so a consequence of progressive's effective movement. Voters had their pick of several progressive candidates in those races, and yes, the candidates who spent more prevailed.

Based on the blowouts in Oregon’s 3rd and 5th District Democratic primaries, is the lesson here just “big spending works”?

With 55 percent of the expected vote reporting in the Republican primary for Oregon's 4th District, DeSpain's lead has increased over former Keizer city councilmember, Amy Ryan Courser. It now stands at 58 percent to 41 percent, respectively.
