TOPEKA — Kansas voters Tuesday overwhelmingly rejected a proposal to rewrite the state constitution and elect Kansas Supreme Court justices, spiking a plan long coveted by Republicans who want more conservative rulings on issues including abortion and school funding. The Kansas Supreme Court must remain fair and impartial for every citizen. Herbert, in a social media video, said the constitutional amendment “is the difference between Kansas becoming Detroit or Kansas becoming a land of prosperity.” The same gambit failed four years ago, when voters overwhelmingly rejected a constitutional amendment that would have removed abortion rights from the state constitution. The following year, more than 70% of Kansas voters approved a constitutional amendment that created a merit-based system.
