My brother, his wife, and my mom are libertarians. My dad is a flaming liberal. Most of my mom's family are conservatives while I have no idea about my dad's family. My wife is extremely liberal (to the point where she annoys me sometimes with it) and I am moderately so. Her dad is super conservative, her mom thinks whatever her dad tells her to think, and her brother and sister are whatever their friends are at the moment.
Most of my friends are pretty to very conservative.
