Doesn't that destroy the allegations of voting fraud in the US? (Not a US-citizen here)

If there was widespread fraud with the voting machines as alleged elsewhere, the voting outcome should have diverged widely from the predictions. The predictions are so close to the actual outcome, and because from what I understand the predictions are mostly based on polling, there couldn't have been much fraud, or am I wrong?

Flippant edit: Assuming of course that Nate Silver wasn't in on the fraud and didn't adjust his predictions accordingly.
