Anything that looks like a political ad on FB probably isn't one. They spend money on boosting posts so that they will show up in the feeds of targeted demographics. It "works" best if the target doesn't notice they are being targeted.
As anyone who has curated a fb page knows, you are constantly being invited to pay to boost your reach. Whether you are selling goods or services, vanity publishing or a political influencer, makes no difference to fb, the money tastes the same.

Electoral advertising on fb is illegal in France (and rightly so), so I was surprised at the sum of 1.5 million euros spent in the electoral season on political targeting. Consulting fb's reporting, it turns out to be institutional -- the EU Parliament itself spent half a million, then you've got Greenpeace and various other non partisan outfits.
