Question: How long is a Senate's term?
Answer: Senators are elected for terms of six years. The United States Constitution lays out the length of US Senator's terms in Article I Section 3:
"The Senate of the United States shall be composed of two Senators from each state, chosen by the legislature thereof, for six years; and each Senator shall have one vote."
The US House of Representatives are elected every two years. And, the election of US Senators are staggered to where 1/3 of senators are up for reelection every two years.
