There's no need for electoral fraud. For the past half century the turnout at the polls for mid-term elections has been around 40%EV. (For presidential elections it's around 60%EV.) All they have to do to win over the astonishing sloth and apathy of the American voter base is rally an extra 2-3% to go to the polls. And they have the built-in tools to do that given that what passes for the "left" in the USA is determined to stay the course on their "Operation: Foot Bullet" plan.
