By introducing her to the right people? You are portraying her political career in such a way that it was nonexistent before she met Brown, which we both know is not true. She was already well educated and on her way up when her relationship with Brown began. What you're suggesting is that without Brown and his connections she would have no political career at all, I just don't buy that, and I don't think you do either. Did she meet people that she otherwise might not have met as a result of their relationship that may have had some influence, sure. But that is all a part of the networking that takes place all over the political spectrum. But to suggest that had she not met certain people that Brown knew would mean she would have not succeeded in her career is flawed.
Now if you're looking for someone to fit your narrative of "it's not what you know, it's who you know" you might want to take a peek over to the right and have a look-see at Jared Kushner. Would Jared Kushner be a current senior advisor to the President of the United States of America had he never met and married Ivanka? Did she not introduce him to the right people that got him where he is today? What do you think of him in that position? Are you supportive of it? Do you believe he's doing a good job? Do you believe he earned it? Do you believe he's deserving of it? Does Ivanka get all the credit? See how that works?
