the R version of votebuilder sucks, but the larger for-profit data-warehousing model has been a big asset almost a decade before Ds caught on (and are still losing digital).

Rs have been leading here for a long time. Kochs funded for-profit i360 which seems to me to be the first, most successful model. They enabled programmatic access to voter data (and even as a D buyer I was able to execute against) while most D campaigns below presidential weren't even really buying programmatic.
