Looking closer to 2004 Election Map

I have already posted few post election articles that point out to silver linings of recent election. Many observers argued that despite the losses on the federal it is difficult to ignore the progressive achievements on state and local levels.

This development has undoubtedly worried many on the right. Hence the rush to claim that the efforts in that state were unsuccessful were premature and it will certainly be in play all the future elections.
