You can find the cert petition here and application to vacate the 5th circuit’s stay of the district court order here. Here is the question presented: “Does Texas’s limitation of the right to cast a no-excuse mail-in ballot to only voters who are ’65 years of age or older on election day,’ Tex. Election Code
§ 82.003, violate the Twenty-Sixth Amendment’s directive that the right to vote ‘shall not be denied or abridged by the United States or by any State on account of age’?”

I say this is risky because it could turn a bad precedent about the scope of the 26th Amendment in the 5th Circuit to one that would apply nationwide. Even if one believes (as I do) that litigation to expand the scope of the 26th Amendment makes sense, this is coming up from a terribly drafted district court opinion and this case has the potential to make very bad law at the Supreme Court. I find the chances of getting relief from this Court on this issue with this record to be very, very small.
