The campaign aimed at recalling California Gov. Gavin Newsom has picked up steam in recent weeks, as more and more voters decide they’ve had enough of the one-time rising Democratic star.

But recall backers still have to submit nearly 1.5 million valid signatures to the California secretary of state’s office by March 17. One critical piece of data shows recall backers could, indeed, be successful: 84 percent of the signatures they’ve submitted so far are valid:

That 84 percent figure is an unusually high rate of valid signatures, compared with, say, a typical petition to put an initiative on the ballot. Observers say that’s an encouraging sign for backers of the recall.

According to the L.A. Times, the 84 percent validity rate means “it’s possible the Newsom recall campaign could clear the hurdle with the signatures its backers say they already have.”

But even if the signatures check out, when voters may go to the polls is unclear – county registrars have until April 29 to review and validate signatures. And once that process, and several others, are completed, “the most likely scenarios suggest a recall election in early November.”
