E-mails on the McCain/John question:

–It’s because McCain is a veteran, hero and all, and military men are normally referred to by their last names. –In a nutshell, it’s because Senator McCain oozes that generation-gap thing. You don’t call people like him by their first names; it’s disrespectful. –Generally, John’s a less common name than Mitt or Hillary or Barack, and specifically, there are two major Johns running this year.
