I think the Texas is lawsuit is asking for a few remedies, and one of those remedies is that these states who have violated election laws can decide their electors. It only ends up at midnight on election day if state legislatures decide that those numbers are the true counts. This lawsuit is not challenging the constitutionality of the votes, it is challenging the fact that governors and SOSs changed laws when according to the constitution, they don't have that power, so it doesn't really make sense that they would go back to election night (unless that's what the state legislature decides...they could also decide to keep the Biden illegal votes or to not send electors at all).
Well, the case doesn't bring up the votes. It brings up the fact that governors and SOSs in these states violated Article 2 of the constitution where it says that state legislatures make laws regarding state elections (paraphrase). Also, the Texas case does not ask them to invalidate votes. Instead, it asks a number of outcomes, but the one that I think is most likely is that these states can decide which electors that they send. At that point, it is likely that some or all of these states decide that they won't send any electors. That's when it goes to the House Delegation in congress.
It's really complicated though, and there are still many ways for Trump to win.
I'm so to the right now that I'm a borderline anarchist. On good days: Maybe the state is okay. On bad days: Delete the state.
