If you give me a political context, I'll just tell you that you're not going to find what you out there in the world, civilians, think is friendship. This wasn't about sponsoring her for a country club membership. This was professional politics. She was chosen for political reasons and she was dropped for political reasons. Not friendship, because it can't be made to work in these settings.
Expediency takes precedence over almost everything in political life.
If you look at the case, nominating her for a job and then withdrawing her for the same job against her will, as a failure of Bill Clinton as a friend, then you're making the mistake that thinking that friendship exists in politics in the same way that it exists out there in civilian life. Politicians are incapable of maintaining friendships on the same type of grounds as people who live in non-controversial worlds. You could be my best friend, and I as a politician could want to give you a particular job, or try to give it to you, and have a public reaction sprout up against that idea, at that point the only thing for me to do, is get rid of you. Because I'm a politician. My need is to do the correct thing politically.
