I'm always very dubious about blame being put on "the media". They're profit-making businesses, and is what's being served something that attracts the readers? Of course the answer is "yes"; there's great interest in how women in public life present themselves, and I think it's fair to say that most of it comes from women.
Angela Merkel must be the despair of these journalists and their readers. Look totally boring, just get the job done.
