While this looks really bad (and I personally wouldn’t doubt there was fraud on a larger scale) this data is statistically irrelevant and doesn’t prove anything in its current form. If voters in each district had a random chance of voting either electronically or by hand, these results would be impossible without fraud. But each district either votes by hand or electronically as a whole. This simply shows that those districts that like romney and clinton are the same that have an electronic voter system rather than a paper method. ATure, it generally holds true across town size, which is further evidence that is MIGHT be fraud, but still unfortunately doesn’t prove anything.
