What is the main idea in this article pls copy and paste it as your answer The Constitution of the United States gives the president a helper: the vice president. However, the Constitution doesn’t say much about what the vice president does, except that the VP is also the president of the Senate (one of the two lawmaking chambers in Congress). But the VP only presides over the Senate to cast a tiebreaking vote or when there is a ceremony. The rest of the time, the vice president advises the president, travels the world negotiating with other countries, helps carry out laws here at home, and is important to many functions in the executive branch of government.
