Just as an FYI, micro-targeting is very difficult to make work (i.e. measure) on Facebook, or indeed any digital ads platform. FB/Google/Twitter etc work by measuring some kind of conversion (pixel hit, app install etc). Micro-targeting in terms of voting doesn't have this signal, and as such any of these ads will be difficult to make work on FB. You can optimise for engagement, but I suspect an ad targeting black voters saying about the 94 crime bill is unlikely to elicit much engagement.
