Interesting, guys. Yeah, the multiple variables at play in Oregon make it hard to say whether Oregon Democrats were consciously pushing back against progressives or if the big spending just overwhelmed everything else.

Ultimately, in congressional primaries, if you are getting absolutely swamped by your opponent with advertising — both negative and positive, unlike in some other recent primaries with spending disparities — you're going to have a hard time. Susheela Jayapal was up against $5.7 million in pro-Dexter spending and could only marshal a few hundred thousand dollars of advertising. McLeod-Skinner faced $5.7 million of outside spending hitting her and boosting Bynum and only aired about $200,000 worth of advertisements. In an expensive media market, that makes it tough to get your message out, let alone respond effectively to attacks.

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.

Of Kentucky's five GOP incumbents, two tonight faced challengers, and both prevailed easily.

ABC News reports that Republican incumbent Rep. Thomas Massie — noted obstructionist and slinger of social media sass — will prevail over challengers Eric Deters and Michael McGinnis in Kentucky's 4th District. With around 58 percent of the expected vote reporting, he leads with 75 percent of the vote. Rep. Hal Rogers — who holds the title of House Dean, or longest serving member of the House of Representatives — had an even easier time in the 5th District. With around 52 percent of the expected vote reporting, he's garnered 81 percent.

While both these contests went as expected, Massie's did see some intrigue. Deters tried to get Massie thrown off the ballot earlier this year, and the incumbent has certainly made enemies within his own party with his hardline opposition to foreign spending and other legislation. AIPAC-affiliated ad spending in this House race was apparently intended to weaken him for potential future runs for higher office.

P.S. — If you're bored waiting for results, I highly recommend browsing the #sassywithmassie hashtag.
