John McCain has something of a reputation for never being more than two clicks away from erupting into a horrifying, dark rage. It's a theme you may have picked up on when reports of his saying some not very nice things to his wife surfaced a few months back. A new chapter of this time-honored storyline has been offered this week by Senator (and noted McCain enemy) Thad Cochran (R-MS), who recalled a congressional trip to Nicaragua in 1987 in which McCain allegedly went buck wild on a member of the country's communist regime during a meeting.
