Will California be motivated to end its idiotic primary system?

Top-two primaries are a particularly silly example of the idea that the solution to political dysfunction is to try to take the politics out of politics. The possibility of disaster is finally causing more people to figure this out:
Democrats have panicked all year at the possibility that California’s primary rules could shut them out of the governor’s office despite the state having an overwhelmingly Democratic electorate.
Now a Democratic strategist is launching a campaign to repeal the California primary system, an effort that is likely to attract serious backing not only from labor unions, but also from some Republicans and third-party organizations.
Under the current system, which has been in place for 15 years, candidates of all parties run on the same primary ballot, and the top two finishers advance to the general election. In some races, particularly in areas that are extremely liberal or extremely conservative, two Democrats or two Republicans have faced off against each other in November.
The new proposal, filed Friday with state elections officials, would end the nonpartisan top-two primary and revert to a traditional primary in which one candidate from each party advances to the general election.
Allow me to summarize the two-top primary:
DOWNSIDE: Possibility of a statewide election won by a party disfavored by a large majority of the state’s voters who would be denied even a meaningful choice in the general eleciton.
UPSIDE: None.
This is not a complicated question.
