But none of them had as many setbacks as Cersei and still pulled through.
I can't name them all, but:
Not respected by Father
Incest cloud hanging over her head
Filandering husband she had killed
Daughter sent away
First son asshole ruler
First son murdered
Tortured
Walk of shame
Daughter murdered
Second son pussy ruler that abandoned her
Second son committed that
Brother/boyfriend left her
The ones you mentioned mainly won until they lost. They didn't keep overcoming L's like she has. And none of them have held as much power as she has. And none gained, lost, gained, lost, gained power like she has, especially at the level of power she has.
