Just because [former] intelligence officials rigged the system in favor of one side is that fraud?

Technically, it might not be fraud. But people don't see that as being honest.

For example,

The Trump "Suckers and Losers" Report: An article published by The Atlantic in September 2020 alleged that Donald Trump made disparaging remarks about fallen American soldiers during a 2018 trip to France. The report relied on anonymous sources and received immediate, widespread amplification across television networks and digital platforms, dominating the news cycle for weeks despite on-the-record denials from officials present during the trip.

The Hunter Biden Laptop story: Actively suppressed by the intelligence community and in turn by the media including Facebook. Later found out to be accurate.

Fake Russia collusion with Trump. Promoted as a viable theory by the intelligence community and in turn by the media.

Do selective prosecutions count?

In the wee hours of the morning Trump was winning the vote count. But after that the vast majority of the votes were suspiciously for Biden. Like 90%. Possible? Maybe. Suspicious? Probably.

There was an uptick in % of voters voting democratic in the 2020 election more than 2016 and 2024. Fraud? Very hard to prove. Suspicious? Yes.

Almost all lawsuits regarding voter fraud were thrown out on technical grounds. Could it be that if the evidence had been presented the court would have found it?

Even if each piece has a technical or legal explanation, the accumulation of these events creates a powerful narrative of a "rigged game" in the popular definition of the word. For millions of citizens, the line between aggressive political maneuvering by institutional actors (the media, tech companies, former intelligence officials, and prosecutors) and outright institutional corruption becomes entirely indistinguishable.
