The US midterm elections will be shaped by a number of key races that could decide control of Congress. Their results will indicate whether Democrats can produce a broad “blue wave” and dislodge Republicans from power.

A Democratic takeover would also affect the president’s ability to advance the administration’s agenda. If Republicans retain control, the balance of power in Congress would remain unchanged.

The contests are therefore being closely watched for their wider impact on Washington and on the president’s position during the remainder of the term.
