You're correct; I misread the article as her being an elected Attorney General, not a US attorney.
I still support undermining any effort of hers to get elected to higher office, though.
How do you 'fight the culture of overzealous prosecution as a whole' without ever making reference to individuals or individual cases? You can't.
Federal prosecutors are appointed, not elected, which makes the effort to name and shame them even more tenuous. Trying to fight the culture of overzealous prosecution as a whole would make it more likely that the elected official who appoints them (the president) does a better job.
