Kansas City Mayor Quinton Lucas is facing petitions, which lists "poor judgement and inadequate leadership" though the Facebook page was launched the day that he extended the mask mandate to combat the coronavirus pandemic.
As Tony KC's site notes, Kansas City's recall law is a malfeasance standard/judicial recall one, which would seem to present a very high bar to get on the ballot. Note that Missouri recall provisions allowing it for charter cities also has a malfeasance standard.
It seems petitioners need to get 13,393 signatures in 30 days to get on the ballot. The petitions are too late to make the November ballot.
