From The Editor: Ever since John McCain announced Sarah Palin as his running mate last Friday, I keep hearing the same message: “Do we want Palin a heartbeat away from the presidency?” While no one’s implicitly saying “McCain’s an old man and could drop at any second,” the subtext is definitely there. None of us wanted race, gender or age to be a political pivot this electoral season, but that “heartbeat” speak seems to hinge on McCain’s 72-years. I’m not McCain’s biggest fan, nor do I necessarily think age doesn’t matter, but this meme makes me uncomfortable. Am I alone?
