Ummmm, sorry but no, sexist headline is a bit of a stretch.
People can hate the CBC or The Sun all they want to, they can mistrust and loathe the Liberals or the Conservatives all they want to, but when I continually see, from both sides of the political spectrum (and I do see it, a lot) pot shots based on what a female politician looks like as a consistent criticism (as compared to their male counterparts who remain unscathed in that particular area of judgement), that, my friends, is sexist.
Identifying someone in relation to their significantly more well known and recently deceased spouse doesn't really measure up in comparison, in my point of view.
