I dunno. You tell me. They invested $10M in Breitbart, $5M in Cambridge Analytica, and gave at least $2M to Citizens United. Bannon and David Bossie from CU ended up running Trump's campaign and CA did their data work. They've backed Bannon in lots of his other ventures. They bankrolled the Clinton Cash book and documentary (c.f. the recent piece that had Bannon and Yiannopolous celebrating its publication aboard Robert Mercer's yacht).
That seems a whole lot more specific and substantial than the vague Soros bogeyman stories about BLM and "paid protesters."
But, yeah, the mega-rich bankroll our political infrastructure, in a particularly un-transparent way. This is the post-Citizens United vs. Clinton world we live in. The Kochs, the Mercers, Sheldon Adelson, George Soros, Tom Steyer... but I'm making a specific allegation about where the money for a specific project came from. Are you disputing it?
Are you disputing that the Mercers bankrolled the Clinton Cash book, or that they're the money behind Breitbart and various other Bannon ventures?
