Americans are poised to elect a new Congress, with control of both chambers at stake as every seat in the House of Representatives and one-third of the Senate is up before voters on Election Day.Every nonincumbent president since 1992 has entered office with their party controlling both chambers of Congress,

A handful of congressional races could decide who has control of the Senate and the House of Representatives. Currently, Democrats control the Senate and Republicans control the House, but both parties only need a handful of seats to flip each chamber.
