I cannot remember where I read this - I am thinking Time.com (as in Time magazine) - but I do know it was something I consider to be be a source that should know better. The article was about Chelsea's wedding (don't make me hurt you by asking Chelsea Who?) and described her mother - in the only description of her mother in the article - as "the former First Lady." Now, Hillary IS the former First Lady, but I would think former Senator or current Secretary of State is a better description.
Heck, I think Mother of the Bride trumps former First Lady.
I will put away my feminist sword now and go back to my cup of coffee.
