What really happened in VA is that McAuliffe restored the voting rights of people who had already served their time and were back in society. This is a power of the governor under VA law and therefore not voter fraud.

It's also worth mentioning that the idea of restoring voting rights for people once they have served their time has bipartisan support--in part because so many people have served time for nonviolent marijuana possession convictions. Take a look at the election results to see how the country feels about marijuana possession these days.
