Rosie is unhappy. While she's the First Lady of the Republic, no one ever asks her for an opinion on things. She's incredibly intelligent and has many suggestions for how the Republic could be made safer, happier, and more efficient, but Dave is always quick to remind her where the power lies. She's starting to doubt whether leaving the caravan business she owned for Dave was a good idea.

Effects of player actions
Rosie is the "good" choice for finishing the Election Day quest. Her quiet and unassuming demeanor will cause the Republic to swell in size, while providing a safe place from the Wasteland for all who enter its borders, as a pseudo-NCR state. She rebuilds the Museum of Dave and renames it The Museum of Dave & Rosie.
Rosie only appears in Fallout 3.
