At this point, all that Texas (and the dozen+ states joining) is requesting is relief from non-constitutionally based Electoral College deadlines while they prepare their complaint.
In the meantime, investigations are proceeding with large and growing momentum and state legislators are starting to firm. Yes, some legislatures have gone wobbly while thinking the administrative deadlines are priority. But if Texas and other states joining them succeed in moving out the administrative deadlines AND the investigations continue gathering speed and momentum bringing heat on legislators, then a shift in priorities can be expected.
So two outcomes:
1) State legislatures use their constitutional powers in disposing of the process of who will be their state’s Electors, or
2) The extended deadline is missed and neither candidate has 270 in which case the determination of who will be President will be taken up in Congress as required by the Constitution.
