Why wait 'til Friday for the Interview?
McCain is clearly a firm believer in the political tactic of releasing bad news late in the day on a Friday. He announced that he fired a number of lobbyists from his campaign on a Friday before a long weekend. He announced that he dumped Phil Graham on a Friday night.
What does it say of John McCain's confidence in his carefully sheltered VP pick that her first interview, even with a suspected softballer, is scheduled for a Friday evening? Clearly the press is aware that they are sheltering her and even some at Fox News are growing impatient with their stalling. So why delay it several more days until Friday unless they're worried it could go poorly? I wonder if they thought this would escape the attention of the press or the public.
