Excerpts:

«The question, however, is whether those more liberal candidates will hurt the party’s chances in November.

….

There’s plenty of evidence that candidates closer to the ideological poles do worse than moderate ones; it’s been demonstrated in political science research, and we saw real–life examples of it in 2010, when Republicans had a wave election of their own against an unpopular first-term president. Although Eastman could certainly still win in a strong Democratic year, we may also look back on her nomination as Democrats’ first “tea party” moment: a general-election opportunity squandered in the primary (or, at least, made more difficult).

….

Jordan, who would become the first Native American governor in U.S. history if she pulls off the upset win, was endorsed by Democracy for America, Indivisible and Cher — three entities not usually known for their influence with Idaho voters.

….

Finally, Republicans held primaries last night too — and, in a role reversal, for the most part they chose more electable options. In Idaho, Lt. Gov. Brad Little, who enjoyed the support of much of Idaho’s Republican establishment, defeated Trump-like businessman Tommy Ahlquist and bomb-throwing tea party Rep. Raul Labrador in the primary for governor. In Oregon, pro-choice state Rep. Knute Buehler fended off two more conservative Republicans with 47 percent of the vote, preserving a potential path to victory for the GOP in the Beaver State’s gubernatorial race.»
