Can they both commit voter fraud? Yes. Are they both necessarily going to commit voter fraud? No. I don't agree with Trump's politics in the slightest, but if there's anything that can be gleaned from the Clinton leaks, it's that her campaign and the DNC at large is willing to play fast and loose to get her elected. There is undeniable documentation that they attempted to subvert the primary election (and succeeded), and it stands to reason that they may again attempt something else in the general election. While that doesn't mean that they'll hack into voting machines, it would be prudent to scrutinize the results.
