I think it's outstanding that you care about Politics, the Country and all that as much as you apparently do at just 17 years old, and you too at just 18 years old, red98teg.
Just be sure when your out there gathering info on the issues, you hear the argument for both sides. Hear what people are saying and why they are saying it, then you can decide for yourself who has the better argument. You don't want to become a braindead idealogue - someone who believes the Republicans are always right or someone who believes the Democrats are always right, neither of them are always right. Be independent minded, be open minded, it'll make you a more thoughful person and a more interesting person.
