Definition and meaning of state senator: State senators are representatives of their constituents in their respective state governments. They are elected by the people and their responsibility is to represent the interests of their constituents in the state legislature. State senators can propose and vote on laws, as well as serve on committees that oversee the budget, taxation, infrastructure, and other important issues. State senators are a vital part of our democracy, as they are the link between the citizens of a state and their government. They have the power to shape the laws of their state, as well as have a say in the direction of their state's future. This makes it important to have independent, reform-minded state senators who are willing to challenge the two-party system.
