No, I wrote the word I meant, but I agree with the point you're trying to make.
I mean that fraud in Robert's argument is an inference as opposed to an observation -- that is, rather than collect evidence of a widespread program of voter fraud and a demonstrable effect it had on the election, Robert reasons that it "must" have occurred based on conditions such as the lack of voter ID laws or turnouts that defy expectations. Reasoning (however wrongly) from premises is "inference" in logic.
The relation
"No voter ID laws at this location" → "Voters must commit fraud there"
is an inference as logic defines the term, and to reason from one premise to another is the practice of inference, even if the "reasoning" is tortured and speculative, as in this case. Or stated another way, one may infer a conclusion from a set of premises although the inference may be of validating or non-validating form.
Stated semi-formally:
States that have no voter ID laws encourage electoral fraud.
The state of Arkania has no voter ID law, therefore
The state of Arkania encourages electoral fraud.
The state of Arkania encourages electoral fraud.
Candidate Obromney won in the state of Arkania, therefore
Candidate Obromney won only by means of electoral fraud.
These are inferential syllogisms. The first is of validating form, but reasoned from a questionable major premise. The second is of non-validating form because it affirms a consequent. Therefore the argument it embodies is unconvincing, for at least those two reasons.
The reason I wrote what I did was to emphasize the difference between inferring one's conclusion by means of tortured and probably wrong reasoning, and providing more direct evidence or observation for the conclusion. Hence I wrote that instead of providing evidence, Robert again tried to provide handwaving lines of reasoning. Trying to infer what "must" be true rather than observing what is true is a hallmark of conspiracy theories.
But yes, he also
implies that electoral fraud occurred, by
inferring that explanation incorrectly from innocuous premises.
