There's better tools. Sort the election totals by precinct size for example. You will see a dependency there, because cheating usually occurs in the larger precincts.

You need to label these lewd images as NSFW please...these bar graphs are giving me a boner.

If you think Benford's Law is useful for helping to spot election fraud you need to see this refutation.

Benford Analysis is dangerous to use for election results. The statistics it uses rely on numbers being distributed across samples sizes that span several orders of magnitude (an order of magnitude means multiplied by 10...so 1, 10, 100, 1000... each increment is one order of magnitude). Election districts tends to be fairly equally sized though, which makes Benford Analysis inconclusive.

It works for things like taxes because expenses tend to have a very large range, e.g. things that cost $1 up to things that cost $10,000. (4 orders of magnitude). It is a very reliable indicator of manipulated expenses in this realm.

But I have to concur it is the wrong way to approach exposing election fraud. It won't be convincing to anyone skilled in the art.
