I started a topic about wanting to understand the guiding principles of the Republican party. I'm also curious about the Democrat Party, as well. So what are its guiding principles, assuming that they have any or that it's not just based on current trends.

For Debate:
1. What are the guiding principles or philosophy of the Democrat party? Is it Liberalism? Does religion play a role?
2. Any books or resources that you recommend for this topic? If so, feel free to post it in this thread!
