Donald Trump made a final appeal to Republican voters ahead of the US midterm elections.

But his closing speech focused heavily on Washington's newly renovated Reflecting Pool, rather than the economic and foreign policy issues shaping the vote.

Polling suggests Democrats could take control of the House, while the Senate remains closely contested.

A shift in Congress would give Democrats new power to challenge Trump's agenda, investigate his administration and block key appointments.

On the eve of the elections, Democratic strategist Nicole Brener-Schmitz and Sudha David-Wilp of the German Marshall Fund speak to DW.
