This is in terms of childhood, major life experiences, someone offering you $1,000,000 if you became a christian democrat, etc.
For me: I was raised U.S. style liberal, and that has stuck around.
I have sort of a "libertarian" personailty, in that I don't trust authority easily, generally hate being controlled and will push and fight against it, and tend to live life relatively individualisticly, some of this undoubtedly seeps into politics.
I have always tended to be a math/science/technology person in terms of learning, so tend to view solutions to political issues as being solvable with enough information. They also should be tested before being used, and will most likely involve a mixture of ideas for running a country.
I tend to not spend much money, so it is quite annoying to see large amounts of budget deficits in the U.S.
I tend to ignore ceremonies, holidays, and such (unless these got me off of school and/or involved presents.) Ideas for running countries based off of traditions and such also have little effect. Similarily, I feel little loyalty to things like schools and cities just because I happened to be associated with them, so things such as "preserving national culture" tend to seem quite strange to me.
