One wonders if anything will come of this?
Nothing will come of it.
In fact it has already been denied by Justice Kennedy. Chief Justice Roberts could have granted the stay but instead referred it the full Court. This is SOP for an application that has been denied by one Justice and then refiled to a second Justice. Everything in the stay (stop the certification of California’s Electoral College vote and the Inauguration) have already occurred so the application is moot.
BTW, an application for a stay requires 5 Justices to agree to granting it.
