The vast majority of the incidences brought to light so far would be categorized as ‘loss of control’, which may or may not include provable fraud - but still plenty of reason for audits, questioning results, and in some cases overturning results. ‘Fraud’ is a much higher bar, as you have to prove WHY these things happened, and intent beyond that.
Also, keep in mind that a lot of these things have been described in terms which go beyond what is demonstrated or actually known. Some of these are likely explainable - but they must be explained, which to date they largely have not been. Some of these things seem unlikely to be explainable.
An example in regards the ‘deleted files’ issue in Arizona, is that the files appear to have been deleted as part of the ordinary process of moving the files to a different location...so the deletion itself is not fraud, nor even malfeasance. The issues there are that the files were not turned over as they are an essential part of the core record addressed by the subpoena, and that they were moved long after any reasonable explanation which has yet been provided - and contrary to statements the MCBE has made.
Enough evidence to recall Electors.
