Ok, I am just sort of curious what issues really get your vote and why. The more thought out your answer is and the more you compare your favorite issues to other major issues and long-run welfare of a nation, the more informative it will be to me.
I have divided these issues up into 3 categories for simplicity's sake. I know that there is some overlap between issues but I am simplifying. Here are the categories:
Economics: These issues are things such as tax levels, wage policies, regulation, tariffs, government programs, poverty, etc. Basically any issue that has to do with money, its distribution in a society, and the use of resources in a society. I would also include environmental issues here.
Foreign policy: These issues are things such as military deployment, treaties, agreements, and how active of a hand the US takes in the business of other nations, foreign aid and things of that nature.
Social policy: These issues are things such as abortion, gun control, homosexual marriage, race relations, free speech, privacy, drug laws, family issues, divorce, often crime, and so on and so forth.
