Trickle or tsunami? Democrats eye gains in US midterm elections

Democrats are seeking to win back one or both chambers of Congress in the U.S. midterm elections, with turnout and the scale of any gains—described as a trickle, wave, or tsunami—set to be tracked as results come in. The outcome will shape the final two years of Donald Trump’s second and final term, testing how a president who has pushed the limits of executive power is affected by the results. Whether the impact is small, large, or nonexistent will depend on the size of Democratic gains and the mood of voters.
