Bush, Religion, and politics

As i was searching for Religion and politic type of videos, i thought this one was interesting. This video of President Bush, talking about politics, and relating war on terrorism, all with references to religion. listening to this, i wonder, is Bush one of the main reasons that the seperation between church and state is vanishing? In this video, he comes across as a preacher, not a leader of the free world. Bushs wars are basically based off of his christian/democratic fundalmentalism.
