How does Texas not have standing?
Seems like you are just repeating a slogan.
But since you are so sure of your opinion, please enlighten me?
Since each State is autonomous is forming election laws, each State can tell the other States to piss off regarding their procedures. Please explain that Constitutional protection the States posses. Do they not have rights in relation to their own laws? Even in Federal elections Article II grants them this right.
There might have been some semblance of combining arguments via other cases into one but that never formulated due to the piling on perhaps.
In any case, there are other avenues the Court might grant cert. Don't get your hopes up though.
