2020 Oregon Redistricting

[Stuart98]

Looks like the courts aren't going to find the map a partisan gerrymander.

Link to the special master's tentative report.

Gotta love the Bend residents on pages 38-41 saying how much they like being with Clackamas.

The democratic witnesses presented interesting (misleading) arguments that have convinced the special master.

Pages 63-67 summarize the testimony of Dr. Jonathan Katz.

• Katz says that "partisan symmetry" is the premier way of evaluating partisan bias in political science.
• Claims efficiency gap cannot measure partisan fairness.
• Claims efficiency gap is inaccurate in states with fewer than 7 districts (how convenient!).
• Admits that the efficiency gap for the plan favors democrats.
• Says that his partisan symmetry model gives democrats 3.86 seats and republicans 2.24.
• Accounting for incumbency, that becomes 4.16-1.84.
• Claims this shows no statistically significant bias.
• Says lack of proportionality does not indicate unfairness.

Pages 68-71 summarize the testimony of Dr. Paul Gronke.

• Gronke says that disproportionality does not demonstrate a gerrymander.
• Gronke considers EG, Declination, Partisan Symmetry, and Mean-Median differences in evaluating the map.
• Gronke compares how the enacted map compares to historical maps under these measures.
• Finds the EG to be well within the historical range.
• Says declination is better than in recent post 1990 plans.
• Claims PS and MMd show a small pro-Republican skew.
• Concludes that the map gives democrats at most a "half-seat advantage" which can be credited to geography rather than intentional bias.
• Claims that a "completely neutral plan" could not be feasibly drawn due to geography.

Pages 71-74 summarize the testimony of Dr. Devin Caughey.

• Caughey says he evaluated the map using partisan symmetry.
• Caughey compares a scenario where Democrats win 58% of the vote with one where Democrats win 50% of the vote.
• Under the former scenario, the bias is 8% in favor of democrats, the smallest possible.
• Under the latter scenario, there's a two seat difference (17%) in favor of Republicans.
• Claims a 50-50 split in the vote is plausible in Oregon, using row office elections (including 2016 SoS) as examples, and claims Democrats' recent advantage is likely to dissipate in the future.
• Says that in a tied election, Republicans have a 68% chance of winning more CDs.
• Goes over MMd, declination, and EG.
• MMd shows a very small pro-republican bias.
• Declination shows a very small pro-democratic bias.
• EG is 8.5% in favor of Democrats, which he characterizes as "a moderate bias".
• Claims the EG may not give a durable advantage to either party, and the EG will shrink the closer the statewide vote-share gets to even.
• Says that the four indicators are split as to which party they favor, and says that whichever the direction, the bias in the map is "unusually small".

Pages 75-77 criticize the testimony of the Republican witness, Dr. Thomas Brunell, who was apparently very bad at his job.

• Brunell says he copied figures he presented from counsel and does not know where figures he presented came from.
• Brunell presented an alternative map but says he knows little about it, including whether it complied with statute or the purpose of features of it.
• Brunell both said that county splits indicate COI violations while also saying counties are poor COI proxies.
• Brunell said compactness was a good measure before later saying stressing compactness is a mistake.
• Brunell said the map was a likely 5-1, but could not quantify that likelihood.
• Brunell complained about the map's disproportionality, but stated that disproportionality is common in the electoral system.
• Brunell did not cite academic or peer-reviewed sources.
• Brunell failed to state the limitations of his conclusions, such as that the EG is volatile in states with only six seats.
• Brunell's initial finding of a nearly 20% EG was only based on presidential results, and when looking at all statewide results the finding was far smaller, at only 7.8%.

Pages 77-78 discuss the alternative map the petitioners propose.

• Petitioners have not provided evidence the alternative is constitutional.
• Petitioners have not presented evidence their districts are connected by transportation links, or that their map doesn't unnecessarily divide COIs beyond a look at counties and cities.
• Katz claims the alternative map has a significant Republican bias.
• Katz says the alternative map would require Democrats to win more than half the vote to get a 3-3 split.

Seems the Republicans got greedy with their alternative map and chose an incompetent witness. Democrats found a bunch of EG skeptic witnesses and Republicans didn't counter. Dems are gonna get away with it.

Nice!

Not quite sure how I missed this, even being election week and all that.

So basically this is the end of the road and it's looking like the final map?

If so the next mission to the squeeze Schrader and hopefully set up a 2022 Primary scene for a candidate who will actually support Biden's agenda, instead of running this whole faux "Centrist DEM" narratives, while he pockets huge $$$ from Big Pharma.

I will miss having DeFazio as my Congressman, but the fact that the composition of the electorate has changed so dramatically in Schrader's new district it provides decent opportunities, especially with the addition of our comrades over in Bend!!!!

Lol, the Rs got owned so hard. Wow.

Our Political Scientists are better than theirs, especially when they try to ship in out of state Carpet Baggers, who apparently have no idea of OR Election law!

Suspect there are some PUB Atlas Posters w/o the gravitas of a PhD, who could have presented a more competent argument.

TJ on Cleve would have done a better job than whatever counsel they got. If he was chosen, the map might actually been very likely to be struck down, for all we know.

Legislative maps upheld: https://mobile.twitter.com/dirquez/status/1462822556721766400

[GALeftist]

Don't know how I missed this, but looks like the ORSC upheld congressional districts as well. Oregon has its maps for the decade.

Gotta says OR Dems were prolly some of the biggest team players this cycle for the national party. They really compromised on the state legislative map, giving several Rs who could've been drawn out safe seats and making both chambers very winnable for Rs in 2022 in exchange for the 5-1 delegation. That's further than any state party has gone on either side of the aisle to get favorable congressional maps

[BoiseBoy]

Independent redistricting has failed to make it onto the ballot for 2022. It will be refilled and will attempt to make it onto the 2024 ballot.
