The big picture: Just halfway through 2021, at least 51 local recall efforts involving K-12 school boards have been initiated this year, targeting at least 130 elected members of those boards.

That's more than twice the annual average, according to Ballotpedia, a website that follows election trends.

It's accompanying the surge of new school board candidates that Axios' Stef Kight has been tracking.

By the numbers: California alone is home to 22 of the current recall efforts. Arizona and Idaho follow with six and four recall efforts respectively.
