Shes going to need to get really creative for that to work. Trump manages to do shit without congress because of corruption, corporate backing, and being nihilistic, impulsive, and being surrounded by yes men.

AOC would be entering a hostile environment and likely wouldn’t be able to tame it, would try to be careful not to do more harm than good, and would be surrounded by well meaning but likely stifling voices of bureaucrats/proceduralists, scientists, and dissenting activists, etc. And she would try to actually listen to all of them, slowing her down and making her easy to undercut by snakes.
