Do you really? Any time they want some group to be exempt form the full force of property taxes, it is solely to avoid repercussions of continuing to jack up property taxes.
AS for redistricting, they currently have one month after getting the census data to redistrict. They want to effectively push that to 3 years if the data is late. The absolutely BEST version of why that is on the ballot is to be lazy. The reality is pretty reasonable estimates have been made, they know what is up, and think it is to their advantage to avoid the redistricting that is coming.
