Did You Know?
Unicameral means "one-chambered", and the term almost always describes a governing body. Our federal legislature, like those of most democracies, is bicameral, with two legislative (lawmaking) bodies—the Senate and the House of Representatives. And except for Nebraska, all the state legislatures are also bicameral. So why did the nation decide on a bicameral system? Partly in order to keep some power out of the hands of ordinary voters, who the Founding Fathers didn't completely trust. For that reason, the original Constitution states that senators are to be elected by the state legislatures; not until 1914, after passage of a Constitutional amendment, did we first cast direct votes for our senators.
