Yes, there's virtually no evidence of election fraud *by voters.*

But we should be concerned about the use of automatic voting machines by election officials to alter precinct results.

One check on this sort of fraud is exit polling, which is used extensively by watchdog groups in foreign elections as a check on their fairness. (In the US, a media pool pays for exit polling.) You know something is up when exit polls are dramatically different from official results, and that statistically, it happens much more frequently in swing states, in districts equipped with automatic voting machines (manufactured by political partisans, incidentally).

I'm in the dark regarding how Ms. Lithwick can reach her conclusion without addressing this form of election fraud.
