Honestly, I think she was just caught up in the weird shit that happened all at once. She married The Donald for his wealth, and figured she'd have to put up with the occasional round of sweaty pig-sex but it'd be worth it to have access to his money and power. When he told her he was running for president she probably said something like "that's nice, dear" and went back to dreaming about banging the pool boy. When he actually started picking up steam she pretty much went into OHSHI- mode, and four years later here we are with her still looking like a deer in the headlights whenever she's on camera. I highly doubt anyone would actively aspire to be her, but then again I also doubt that anyone would have aspirations to be Mike Obama, either.
