The very fact that Obama et all have spent over one million regarding this should be proof enough that this endeavor is a futile one. It will become the latest conspiracy theory and therefore, like all conspiracies will on long after Obama has left office. The time spent on this is time that could be spent on urgent battles such as Sotomayor, universal healthcare, veterans benefits, and the war on terror.
Obama hasn't spent dollar one on this, it's all come from his campaign. And one million dollars is what, a fraction of a percent of the amount of money he raised? This is petty cash for them.
