No. First, Texas has no standing to sue. It's own state laws were not violated and it has suffered no damages from what occurred in other states. The Texas Solicitor General would not even get involved in this lawsuit, it was left to (the indicted) Ken Paxton.
The federal constitution refers to the method of selecting electors. It is not about state election regulations involving dates, etc. So, there is not even a federal constitutional issue in these cases.
That's the first question I asked. How would they show they have standing?
