I assume they had a board meeting and went over the metadata and it pointed him that way statistically as the best choice for Facebook's continued profit margins.

I suspect Facebook's share of the market with younger people is dropping off so he's reaching out to adults (politically speaking as well) in order expand his potential market.

 I see a ton of Conservative information on Facebook, do you use the platform or only read about it?

 The Trump campaign used it like crazy, millions of ads distributed to millions of Conservative users.  There is a lot of information out there regarding the strategy and how effective it was.

There's no satisfaction to be taken from that admission of speaking from ignorance.

"RNC spent $4.2M in the last 90 days on ads... "

 Yeah anyone on the platform knows there's a ton of pro-Trump on it.  The metrics released by the Trump campaign, which is a small sampling "to preserve strategy integrity" is still in the multi-millions of supporters on Facebook.

 I don't know anyone that actually uses Facebook that can't find Conservative based material and groups.

 I think a big part of the problem is it used by such a large age pool, and its hugely influential, so we end up with these massively misinformed political hearings where Zuckerberg has to answer to the Judiciary Committee really ridiculous questions.  Like "How do you sustain a business model where users do not pay for your service?"

 Never heard of radio Congressman?  Network Television?

 So people with zero knowledge of how the program works want to sit around telling other people what's on it, how it runs, and what it should do.  How much sense does that really make?
