She’s trying to save face. She has no power or jurisdiction here.
Once she dismissed the case and it headed to the 11th on appeal, she lost any actual ability to do anything regarding the case with the exception of orders she made that were not on appeal (there were none).
Additionally she has no power to release volume 2 of the report. That power is only held with the DOJ. Jack Smith even stated that it should not be released as long as the case against the conspirators still survived. Releasing that report would likely damage the case against them. However, if that happens, it would likely mean Trump would not need to pardon them to stop the prosecution. While the report may be seen as a threat to Trump, anyone who supports him refuses to believe he did anyone wing and I doubt anyone who would actually read it would have a change of heart.
Seems like a lot of people see value for themselves in bending the knee to the Cheeto Mussolini, not really shocked that a has been who most people have probably forgotten about would do the same.
I don’t think most of MAGA is actually MAGA but they now have a group of ready made followers to feed their bank accounts, careers, and egos.
