What do you mean you don't get to question how fair the elections are? The sitting president of the entire country has questioned and investigated them. No one has stopped questioning and investigating them. People literally stormed the capital over it and had effectively zero real long term consequences in the overwhelming majority of cases. Dozens and dozens of lawsuits, none of which amounted to anything, even when they were in front of Trump appointee judges.

The precedent, if anything, is that we will tolerate people upending the whole public discourse and portions of the government for years over nonsense that never had any evidence of anything occurring on a level that would impact the elections.

Meanwhile, Trump has spent the entire administration trying to restrict the ability for demographics that won't vote for him from being able to vote. Openly. Sometimes honestly, but mostly also blaming all of it on the election he lost and claiming it's to stop the voter fraud that never actually occurred.

The precedent that was set is that questioning the election can become dogma for a political party no matter if there is absolutely zero evidence of what they are saying happened.
