Obama, McCain and Ageism

Despite being an Obama supporter, I criticised him for the sexist dogwhistles he used against Clinton, as he talked about her “periodically… feeling down”. Now he’s talking about McCain being “confused” and “angry”, which arguably are ageist dogwhistles. What do you think about these? I find myself wanting to say that when McCain gets facts wrong there’s nothing problematic in calling him “confused”, or that when he acts angry it’s fine to call him “angry”. But I worry that partisan loyalties may be muddying my thinking on this.
