Hillary Clinton vouches to continue until the last primary. 
However, it is not beyond belief that she will continue well into the convention running an insurgent, disinterested or Obama-supporting campaign.With Hillary you just can't tell. But given the realities, especially after Edwards endorsed Obama, are Hillary's actions or lack thereof telling us something about her Presidency should she somehow be elected?
While most pundits speculate about her motives, the reality is that she discounts all the parameters that counts. The total delegate count, the Obama superdelegate advantage, Obama's insurmountable money advantage, Edward's endorsement, and the damage to the party -- all these do not seem to matter to her. Indecision, the pundits tell us, keep her options open.
But there is another possibility. It is that in face of uncomfortable realities Hillary is simply incapable of making the hard decision to concede. The politician who kept pounding us with her messages that she is ready from 3am on day one to make the hard decisions, seem paralyzed and unable to make the hard decision. She marches on as if facts do not matter. Has she become like a shark who cannot stop swimming lest is stop breathing? Or perhaps she is like Bush who marches on in Iraq with total disregard to realities. He hopes that history will vindicate him. Is she hoping the same?
Hillary started her campaign as the front runner. Then she ran a terrible campaign, some say it was political malpractice, that brought her to where she is now. Was she unaware of the Obama's success? She certainly was, yet it took her months before she shook up her campaign. When she finally got it working it was too little too late. What took her so long to change? Was it once again an inability to make the hard decisions on time?
If these two are any signs of what her Presidency would look like, then we may all be spared a Carter-like administration. But yet again, with Hillary you just can't tell.
