In the American political arena the major parties Democrat and Republican represent the two diverse perceptions of our country–one from without and with from within. The Republican traditionally looked at the country as a whole that interfaced with the rest of the world, while the Democrats excelled in the demographics of the country looking at the welfare and rights of the individual.
The reason this political system has successfully evolved is because it mirrors creation made of two light called Sovev Kol Olomim/Surrounding Light and Mimulai Kol Olomim/Filling Light--an inner light and a peripheral light.
The inner light nourishes life while the outer light holds creation in the infinite care of the Creator. Whenever human endeavor strives to mirror creation success is inevitable.
