> Wasn't Facebook caught scrubbing positive conservative news stories in the past? I could see secret deals between facebook and political parties regarding the consumers of their "free" internet.

Yes but it wasn't because of a secret deal (and would likely never be such). SF/SV just leans more liberal and its conservatives are generally libertarians. So, natural biases were likely the only cause and why pay for what you can get for free?

I think every Democrat would agree the GOP being killed off by the Libertarians would be a good thing simply because it narrows the scope to fighting over financial/economic issues and related civil rights issues. Rather than fighting over things like abortion and having the GOP quietly use building codes and other tricks to kill abortion clinics anyway.
