What recourse do one or more states have in the face of evidence that one or more other states have failed to produce — intentionally or by negligence — an election process and ballot count with integrity?

If the Supreme Court is not a forum where such disputes can be aired and resolved, what forum is there? Congress is controlled by the same partisanship that is said to be the cause of the irregularities at the state and local level. //

I have concerns that the Justices will view these matters as nonjusticiable — meaning that while there may be validity in the claims raised by Texas, the claims are political disputes between the partisan branches which they must resolve outside the judicial branch.

What other means might exist for Texas to resolve its claims is where the difficulty sets in.
