WASHINGTON — GOP Sen. Joni Ernst has won the Senate race in Iowa, securing reelection to a second term after a surprisingly competitive campaign.
Ernst's victory over Democratic businesswoman Theresa Greenfield moved Republicans a step closer to retaining their majority in the Senate, where they now have a 53-47 advantage.
The contest drew national attention because Ernst's unexpectedly tough race was seen as a warning sign of the toll Trump's political struggles were taking even on once-strong incumbents.
