I just got back from seeing this, wem, and I don't think you're portraying it accurately. Firstly, there are two significant female characters, the intern and the reporter, not counting his wife.
The intern (main female character) is shown as intelligent, assertive, but flawed. She is shown as having a strong interest in politics, she mentions her university and her work on the campaign - hardly her only backstory being that she has an important father. I'm not sure why you think the only interesting thing about her was her father - did you not watch the same movie that I did, where the plot centred around her decision (SPOILER) to have an abortion?
The reporter was shown as just as aggressive, cut-throat and manipulative as the male politicos. They even spent some effort to make her 'ugly' (well, movie-ugly, which equals scruffy hair, disheveled clothing, but still perfect teeth, skin, and symmetrical features).
Correct, it failed the Bechdel test, but it's not as bad as you're painting it, imo.
