How much did Trump and similar non-Russian PACs spend on microtargetted facebook ads, compared to Russian intelligence? Your article contains no hint of this. I think we're all aware that Russian intelligence was buying a lot of ads on social media, but I'm trying to understand the relative scope of this. To be frank, the scope of Russian propaganda seems dwarfed by domestic propaganda. The propagandists who deserve the most blame are probably Americans, or were paid by Americans.
