Retire? Oh you're funny.

She is 100% planning on dying in office. She's obviously one those people who are obsessed with leaving a "legacy". In her mind she's going to be remember as the first female member of the House and a groundbreaking feminist who made way for others, etc.

Which would have probably stuck if she'd retired a decade ago. Now she's going to remembered as a greedy ghoul who intentionally sabotaged other politicians and held back society to enrich herself. This is too little, too late.
