No, it's just a play for votes. Short of the government getting DNA tests from everyone living in the US and then researching their ancestry, there is no way to determine who was a slave and who was a slave owner. Maybe that's one of their goals though.
Knee-jerking Democrats think this is a simple black vs white issue. It's not. To really, really complicate matters there would actually need to be three categories: 1. slaves 2. slave owners 3. people who were neither slaves nor slave owners As if separating #1 and #2 wouldn't be complicated enough, what would we do with #3? What would we do with folks whose ancestors included both #1 and #2? The whole thing is nothing more than a stupid attempt to pander to black votes.
That's the tip of the iceberg. Imagine a descendant of a slave owner and a slave who is part slave owning Cherokee. Leftists never think past their feelings.
Democrats for their own good need to drop this reparations stupidity, it is overwhelmingly opposed by Americans. What would the pro-reparations crowd do with someone like Obama? He is a millionaire, his black side wasn't involved in slavery, unless it was on the 'business end' in Africa, and his white mother's family were slaveowners.
By definition, a POTUS isn't a fringe player. For that, see the Democratic clown car trying to beat Trump.
