THE 15% GUY HAS AN UPDATE
When I first posted the 15% Band, I compared Republicans vs. Democrats, so it covered 30 Senate races.
Now that results are nearly final, I updated it to include every vote: Republicans, Democrats, independents, third parties, everyone, in all 35 Senate races. Then I ran a new regression analysis. Once again, the number came back .85.
If this stands up to closer scrutiny, we know either what voters did (seems unlikely to be that uniform) or what Dems did. Somehow.
If the latter, then it now becomes essential to learn HOW they did that.
