> For instance, before the election stuff is dismissed as “no injury” after the election it’s “no way to rectify”.
You have to be more specific here. The way you're describing it, sure, that may sound unfair.
But let's look at what was being claimed before the election. Then, lawsuits were about restricting which votes could be counted and when. The Trump campaign and Republicans were very concerned about drop box votes, which they felt could potentially be fraudulent. Mind you, they didn't bring evidence that the votes were fraudulent. There were just theories that they could be, and therefore should be summarily rejected. Cases like these were rightly dismissed, because they didn't state an actual injury, and they didn't even provide evidence of a potential injury. You can't sue for anything with no evidence and expect to win.
The net result of accepting the Trump campaign's claims at face value would be to disenfranchise voters without any evidence their votes should be discarded or made harder to cast. Weighing definitive disenfranchisement against potential and unspecified voter fraud leans in favor of the latter.
As for "no way to rectify" after the election, that's not quite true. There are processes within each state to challenge their individual elections after they are held. The Trump campaign went through that process and lost. One main reason they lost is they didn't allege any fraud in court. Think about that for a moment. The entire Trump campaign and the GOP apparatus was on TV, all day, every day from November to January claiming fraud.
But when standing in front of a judge, they demurred. Why? The obvious answer is because they didn't have proof of their claims. If they did, they would have provided it. But they didn't have proof, so they didn't make the claim in a court of law where it would have legal ramifications, unlike TV.
Moreover, when the relief they wanted was untenable. They wanted things like entire elections to be thrown out after they were certified. They wanted to rerun the entire presidential election at the national level. There's just not mechanism to effectuate what they wanted to happen, which is they wanted the courts to install Trump as POTUS over the will of the electorate. Indeed, there's no way to rectify their perceived injury, and telling them as such shouldn't cause a beef in anyone who has followed the state-level recounts and audits. Because the Trump campaign lied, and anyone who still is pushing the idea the 2020 election was stolen from Trump was lied to, or is still lying to this day.
