Fortunately, given the great American tradition of holding a vote for 300 million people on a single day and on a working day when middle class people cannot easily get to the polls, things have worked out well for Republicans.
In a recent rant, John Oliver examines the one study which suggested voter fraud, i.e. a person voting more than once on election day, may actually occur, and, it turns out, when you look at that study, what it really shows is this almost never happens.

Ah, there is the essence of concern for the integrity of democracy.
