I think I'm a moderate libertarian.
On economic issues, I believe the government should basically stay out of the way and respect private individuals right to contract with one another. I don't have too much of an issue with the government cracking down on fraud rather than letting the free market deal with it, because capitalism requires information flow, which can be tampered or severed. The primary "liberal" perspective I hold with respect to the role of government is that I think the government should enforce regulation that requires private organizations to consider externality costs. Drilling cheaply may be the least economically burdensome approach, but create economic waste far in excess of the costs the company itself shoulders. That leads to inefficiency. However, I think these determinations should be made by states more so than federal organizations, simply because the larger and more bureaucratic something becomes, the less capable it is of doing anything right. In summary, we need some regulation, we have way too much today, and the goal of government should be maximizing efficiency and individual economic freedom.
On foreign policy issues, I go back and forth. By and large, I think we need to place a larger burden on the rest of the world to manage its own ***** There is a time and place for intervention, but I don't know that we have the appropriate level of discretion.
On social issues, I am moderate - I think gay marriage should be legal, I think weed should be legal since alcohol is and we waste a lot of time worrying about it, and I think abortion should be illegal, which arises not out of any religious perspective but simply because that the fetus is comprised of unique genetic material and therefore isn't part of the woman the same way her hand or liver are. As it is a unique human who is biologically alive, I think it should be afforded the same rights as an infant dependant on its mother.
Ultimately, that all leads to a relatively coherent philosophy in which the government basically leaves me alone.
