The worst-governed state — Illinois had triple the population loss of the state with the second-highest out-migration between 2010 and 2020 — is contemplating another incentive for flight. On Feb. 16, a joint committee of the state legislature will decide whether to turn into a legal requirement the State Board of Education’s recommendation that — until a slight rewording — would mandate that all public-school teachers “embrace and encourage progressive viewpoints and perspectives.” If the board’s policy is ratified, Illinois will become a place congenial only for parents who are comfortable consigning their children to “education” that is political indoctrination, audaciously announced and comprehensively enforced.
