There will always be fraud going on in every election, in every country.
It's just stupid to think otherwise, now the question is to what extend and would it have changed the outcome. The answer is obvious.

That actually isn't the question in my mind. If there is fraud it should be investigated and prosecuted regardless of whether it would change the result or not.
I'm more interested in improving things for future elections, and for that reason I don't think it makes sense to dismiss accusations of fraud, widespread or not.
It seems pretty clear that there are lots of things we can do to improve the way in which we carry out elections. Devising systems that are resilient to fraud and are transparent such that accusations of fraud are easily resolved is important for injecting confidence back into the process.
