Some wiseass once said a week is a long time in politics.
And the ramifications of human behavioural psychology are about as complex as predicting the weather.
Wright, unwittingly it seems, has done a big favour to Obama by his latest bile. Obama has made a clean break- and either he genuinely meant it, or he's such a good actor he leaves Pres Raygun for dead. These days, it doesn't matter in Politics.
Too little, too late? Ultimately we're all guessing, and you needn't bother putting your best guess here really- it will only be a function of whom you want to win.
The electoral camjpaign is of course about to change, to the Home stretch- the actual election. Of the three left standing, only Hillary was even mentioned as a serious contender about six months ago.
You know who I want to win, but that means nothing. No contender can be written off at this stage. It may be the case that Obamas 'ordeal by fire' will prove to be the right thing at the right time, in retrospect. Both him and Hillary are more concerned about the Dem nomination than McCain at this stage. That, of course, will change quite soon.
