In a weak, small paragraphed attempt to deter you, there is a greater chance that McCain would not bring the same 4 years, than the chance that Obama will bring us immediate improvement, hiding behind severe long-term issues.
As they say, history repeats itself, and Obama's policy will bring more frightening results than FDR's New Deal, which if you remember from your AP history class did wonders initially, but soon after left more people jobless and multiple generations footing the bill to save a declining economy some 60-70 years ago.
While Obama's plan for being our savior reminds us all too greatly from the only other attempt to revive us from depression, McCain we know will logistically approach the scenario, and should not be immediately carted off as another Bush.
