Certainly my parents and their beliefs played a major role in the beginning. In my case it was more of watching my parents struggle finanacially and try to survive with very little money and no government assistance.
Though my dad was a disabled veteran, and I had relatives killed in wars, there was never much direct political discussion in my household. It was just all about survival and respecting whomever is in power particularly if they are trying to do what is right for us. There was not any strong views one way or the other.
I didn't need a label to know where we all stood as a family on political issues. And not only as a family, but as a member of a minority group, in a low-income area and seeing the homelessness, hunger, and scary struggles of so many people everyday, those are all what have also affected my political socialization.
And like the household I grew up in, my husband and I do not include long political discussions, political TV shows or radio shows, or political readings in our everyday lives. We support who we think is the best person for the job, and just let things take their course. We discuss politics from time to time, but in more of a neutral, low-key manner. I think our daughter will be able to grow up and say, just as I can say, that political discussions were a small part of what she remembers growing up in her home.
