At the state and local government levels as well, there are many satisfying opportunities open to you. These are often the best places to launch yourself in the process. At all levels and in all branches, power is divided and shared, as it should be. But only those inside government have power. All others can have, at most, influence.
Parties are vehicles to power.
Grassroots political groups can propel people to power. But only people in government wield legal power and make public policy. It is not enough for conservative Republicans to have influence. If you or others like you do not devote all or at least some of your lives to service in government, the power of government will be in other hands. People who do not share your principles will rule.
