To be clear, I didn't work on voter suppression projects. I was made aware of them while I was there.
My understanding of what the company was intending to do—I believe at the instigation of Steve Bannon and some of his colleagues in different packs—was to create lists of predominantly African American voters and then look at what types of messaging would disengage them from politics further, which would then reduce the likelihood that they would vote.
There are different definitions of voter suppression. The most egregious form would be to actually go and try to deregister people from voting, by what's called vote caging. That's not what I'm talking about. What I am talking about is finding things that will make politics so unappetizing or confusing to a subset of voters that they become less inclined to actually vote or engage with the democratic process.
