Possible voter fraud vector in Missouri

The Senior Tax relief bill was passed by the Missouri Legislature and signed (SB190) and gives seniors a break on property taxes. Here is the thing, It is up to local governments, and the big blue centers, St. Louis and Kansas City (https://www.jacksongov.org/Government/Departments/Collection/Senior-Property-Tax-Credit-Program) jumped right on it. Boone County was a bit slow but all wanted clarification. Here is the interesting part. To get it, seniors must provide all the property details on the application, provide proof of ownership, a valid id and have the thing notarized. It has to be renewed yearly! So why would all the blue counties get on it? Why so many hoops, when they have all that data in the county database. It is unlikely they have the age of the owners and one can assume that older voters find it hard to get to the polls the older they get. Last election we heard plenty of stories of people getting to the polls and being told they already voted. This tax relief and the associated forms creates a ready-made hit list in these blue counties.
