Hilary Clinton's campaign to win the Democratic nomination appears to be in freefall after a change of strategy led to a senior aide resigning in disgust.
So stretched are Hillary Clinton's campaign finances that she is taking the risky step of putting in no real campaign effort in the smaller states, and will instead bet everything on winning big in big delegate rich states of Ohio and Texas.
This is the same strategy that Rudy Giuliani tried in the Republican race when he chose to sit out the early primaries with the intention of winning big in Florida. Instead, all that happened was that he lost big in Florida and made himself look like a prize idiot.
Obviously the Clinton Campaign would not choose to do this if funds and support were going their way, but after Saturday night's clean sweep of four states for Barack Obama, all with embarrassingly large margins of victory, the tide appears to have turned decisivly in Obama's favour.
As a keen watcher of American politics who feels that America's name has become a dirty word in George W Bush, I have to say I am impressed by Obama and hope this is the decisive moment in his campaign to win the Democratic nomination.
