Above is questioning by Ted Cruz of some guy (a liberal academic) about voting manipulation. Not stealing votes, but Twitter, Google, Facebook etc. “pushing” to go out to vote, but just sending out the reminder to democrats.
He estimates that in 2020 this pushing (as well as manipulating search results, which doesn’t cost google, etc. anything) - he estimates they could get out 2.6 to 10.4 million more votes to the democrat.
