If she's were only a B- Conservative, the 'force multiplier' of her gender and ethnicity would alter the flow of political though in America. She'd be an A+ Republican, which would hasten the destruction of the liberal victimization machine. Looking at the big picture, it's far better to get her in, than someone more conservative.
