Chicago alderman JoAnn Thompson died on February 9. She had been running for re-election in the February 24 non-partisan city election, so naturally her name was already on the ballot. The Board of Elections is removing her name from the electronic ballots, but some votes will have already been cast for her by early voters. Those votes will be tallied, but voters on election day will not find her name on the ballot. See this story. Thanks to Electionline for the link.
