Cersei Lannister as well. She does such things as dismissing the idea of paying the money that the realm owes to the Iron Bank of Braavos (an institution that has a reputation of replacing rulers that don't pay debts), as well as spending a very large amount of money building an entire fleet of warships, then handing it over to a man of questionable integrity and reliability, just because he vaguely resembles her childhood crush. As soon as she's imprisoned in A Feast For Crows, the guy makes off with every ship — naturally. Or, how about empowering a group of religious zealots who have had a long history of rebelling against the Crown, and who clearly still hate the noble elite? The only thing she succeeds at during her stint as a ruler after Joffrey dies in A Storm of Swords is running the Seven Kingdoms into the ground at an impressive speed, in the process amusing Littlefinger greatly andmaking the realm that much easier for Varys to help Prince Aegon Targaryen VI — the lost son of Prince Rhaegar Targaryen (there are question marks) — take for his own. In fact, when Cersei's competent uncle, Kevan Lannister, takes over the Regency, Varys kills him, as he was actually beginning to stabilise the realm.
Cersei doesn't fit this trope. Sure, she's both stupid and evil, but the definition of Stupid Evil is a character that does something evil despite knowing it won't report them any benefit or even may go against their goals. Everything Cersei does is with the intention of obtaining some sort of benefit, and her actions blowing up in her face is more of a(n admitteldy extreme) case of Didn't Think This Through and overestimating her abilities.
Plus, a lot of the actions detailed are deprived of context. For example, Cersei didn't rearm the Faith Militant just for the hell of it, it was done in exchange of the Church forgiving the Crown of a debt of more than one million Gold Dragons, plus Cersei thought she could use the Faith Militant to get rid of Margery Tyrell. Was she shortsighted? Extremely so. But she carried those actions with the idea that they would report her some benefit.
