Drives me nuts to be honest.
I don't think it is a female only issue though . Boy can some male politicians come in for some flack by the media and public alike, it can appear quite cruel at times.
Fashion, hair style, trouser length, looks, body weight, boobs showing, skirt length, sexuality etc. are often used to try and belittle/deride our politicians . I suppose it has always been the case.
The 'tone' of how a report or conversation follows can be quite interesting and usually tells you more about the personality of the person writing or talking than the politician they are musing over. Why some feel the need to be so puerile or at times downright nasty eludes me but each to their own I suppose and some commentators make a damn good living out of it.
Sad really but not likely to change, people enjoy doing it, unless ofcourse they are on the receiving end then it is a totally different matter.
