Voter Supplement for years prior to 2020?

I seem to be unable to locate the voter supplement to the years before 2020 on the IPUMS CPS web site. Please let me know where I can find those data? Thanks.

All of the supplements are available in the sample selection menu on the IPUMS CPS website. To get to the menu you would hit Get Data on the IPUMS CPS homepage followed by Select Samples on the top left. Once you’re on that page, you want to select Basic Monthly, followed by Supplement Topics, and Voter. There you will be able to select voter supplements from 1976 to 2020.

Thanks a lot.
