I'm archiving all of my FT data as we speak and will download it once it's ready. Admittedly, it may take some time to sort through given I had hundreds of FT data sets and I wasn't very good at organizing them.
With regard to the 2016 white vote numbers specifically, I believe reagente uploaded his data to his own FT account (however, I hosted the page on which it was displayed), so he will need to double-check to make sure this data is secured. FT data will remain downloadable until March 3.
This good to know
