I discussed this issue with our Election Administrator, who also happens to be our Clerk and Recorder and asked her to weigh in on this discussion. She formulated this reply:
Actually, the address library in Mt Votes was converted by our software provider before each county went live on MT Votes. In Gallatin County, your department provided an address table to our previous software company that uploaded the information into the Voter Pro software from CSA in Billings. Then our MT Votes provider with the help of CSA in Billings took the address library and converted for the appropriate fields in MT Votes before we went live in which was about October of 2005.
We cannot automatically upload the data into MT Votes. I am a member of the technology team that works with the system for the Secretary of States’s office. (Yellowstone and Missoula Counties also have a member on the team.) Our team decided that the cost involved to upload the addresses was not worth the time or effort. It only happens once every 10 years, and even though every county is on MT Votes, the way the address libraries are used can be slightly different. – For example, several counties use legal descriptions instead of actual street addresses. Some small counties only have one house district and one precinct so they have very little change that has to be done.
Our team determined that it was safer to do the manual update in a controlled manner. The Secretary of State has provided each county election administrator with a scheduled time-line, and we will be doing training for the counties that need help. The changes in MT Votes have to be done by July 15th, 2013 so that we will be able to conduct the Municipal Primaries in September with the corrected address libraries.
This seems labor intensive for counties with numerous changes, but in our case, the Elections Department will be taking on that burden. I don't know if that will be the case in every county so you might want to have this discussion with your Elections Administrator in case they are expecting your GIS staff to do the manual updating into Montana Votes.
