Fraud in the form of the outcome of a specific election being different than the actual votes counted: well, probably not super widespread or rampant but not exactly non-existent.

Disenfranchisement, gerrymandering, polling place reductions, unequal representation, etc. are, however, quite rampant. Not all votes are equal in the US, and not all voters are treated as equal either. The result is the same (subversion of democracy), but the tactics are different.
