Another yahoo yelled out “kill him!” today, and he/she wasn’t referring to David Letterman. It happened this time at a Sarah Palin rally near Scranton, while she was being introduced by Republican Congressional candidate Chris Hackett. Palin said nothing, of course, when she got to the mike about this kind of talk being unacceptable. A few minutes ago MSNBC’s Keith Olbermann opened up on John McCain with both barrels for not repeating clearly and emphatically to the faithful that hate epithets are out of bounds.
