Why are you republican or democrat?

I am republican because after a lot of hard work and a little luck I have become financially successful. The republicans help me keep more of my money. On the social issues I really don't care one way or the other. I think most of the decisions should be left to individual states. What is right for cali's may not be right for texans. I know this is very brief, but don't most people choose on just a few issues. Thank you for your input.
