What if Facebook chose to send voter registration reminders only to supporters of one candidate? What if, on election day, Facebook chose to send voting reminders only to that candidate's supporters?

Facebook's power is nothing compared with Google's. Controlled experiments my associates and I have been conducting show that Google has the power to shift as many as 13 million votes using biased search rankings and search suggestions. Such manipulations are both legal and undetectable.
