“You’ve heard the old adage ‘follow the money.’ I follow the vote, and wherever the vote becomes an electron and touches a computer, that’s an opportunity for a malicious actor potentially to … make bad things happen.” — Steve Stigall, CIA cyber-security expert, in remarks to the US Election Assistance Commission

Primary election rigging in the coming weeks and months is all but assured if American voters and candidates don’t take steps to prevent it now. Evidence that US voting systems are wide open to fraud and manipulation should be taken seriously in light of the unprecedented high-stakes elections we’re facing.

Not in recent history have American voters been presented with such radically polarized candidates, forcing a crucial choice for the direction of our future, and possibly upending long-established centers of power.

It’s no secret that US primaries have been tightly controlled by the two ruling parties, usually to the benefit of their favored candidates. If this internal manipulation (some might call it rigging) is not publicly condoned, neither is it loudly condemned.

This year, however, the primary season is shaping up to be a battle royal between the political establishment and outsider insurgencies who are challenging the party elites and defying their usual filters, money and manipulations. And it seems all bets are off.

As a brazen Donald Trump kicks down the door of the GOP, tens of millions in super PAC dark cash has (so far) failed to buy the candidacy for a lackluster Jeb Bush. Accusations abound that Democratic National Committee Chair Debbie Wasserman Schultz has stacked the deck for Hillary Clinton. Yet nothing – not even corporate media’s censorship or outright hostility toward Bernie Sanders – has blunted his skyrocketing grassroots campaign.

You might ask: What is left, then, for the party powerful to ensure outcomes in 2016? Would any of them be so desperate as to actually rig the final vote count? Could they?

Indeed, they could.

But to be fair, so could a lot of other people. Local fixers, insider operatives, rogue hackers and even foreign countries could all rig US elections – in whole or part, in 50 states and most of the United States’ 3,143 counties – electronically, and without detection.
