An Obama presidency will, almost no matter what, be a welcome relief and major improvement on the current administration. The impact of that alone should not be understated. If, however, Obama is a four year interlude between Republican administrations like Carter was, or if, like Clinton, he fails to pass any major legislation or build the party, Obama will have been a disappointment. Moreover, a truly successful Obama administration will not only succeed legislatively, but strengthen the Democratic Party moving forward.
