So none of these 10 cases will now move ahead?
The ten cases are all back in limbo, now. They have not been refused a grant of certiorari, they have not been granted a writ. They are held, as is.
One positive thing is President Trump has been appointing more originalists and textualists to the lower courts. Even the 9th Circuit now has about 40% judges who were appointed by Republicans, which is only a slight indicator they may not be progressives.
The more judges President Trump appoints, the harder it gets to keep treating the Second Amendment as a second class right.
