I'm not convinced any court, anywhere, will hear any case regarding the 2020 election—even if it would have been willing to do so in past elections, or in the future, and even if a judge personally believe's the case has merit. Certainly that's been the case so far.

To do so in 2020 is to legitimize Trump's assault on the country, and I just don't see the courts doing that.

It's better to just dismiss every case regardless of the merits. Republican voters aren't going to do anything about the election result once Biden has been inaugurated in January.
