Under CA's "jungle primary" system - against which I voted, BTW - the top two vote getters would be on the November ballot, regardless of party. The polling in the past couple of months had Bianco, Hilton, and Swillwell (alphabetic order) as the three highest %s. The reason both Rs have been so high is that the Dems have something like 8 candidates spreading out Dem potential voters. From that perspective, the Dems "needed" to cull out most of their candidates to avoid the chance of the November ballot having the two Rs and no Dem.
What has me thinking that Dem/Prog political operative Cheyenne Hunt is acting indy is that the Dems simply getting rid of the top Dem makes no sense to me. What does make sense to me is that Hunt's revelations made Swillwell unviable, and the Dems reacted swiftly to make room for ... ??? That swift reaction implicitly means that the Dems and their MSM-shills know enough about Swillwell to know he had zero chance of dodging the Me-Too Bullet. The degree of certainty might vary, but dozens of Dem pols and Dem-shill MSM folk knew what Swillwell is, probably years, even a decade, ago.
Going off into wild-ass speculation ... info about Swillwell's divorce from his first wife is not, AFAIK, online. I have no problem with that. I wonder if it was due to Swillwell's horndoggery and first wife learning about it. I wonder, on another but somewhat related tack, if second wife learned about the horndoggery from Cheyenne Hunt's revelations or if their "marriage" was, ummm, "open".
