The political fates of Iowa Republican Sen. Joni Ernst and President Trump are intertwined, potentially costing their party Senate control or the White House or both.
Ernst was swept into office on the crest of the 2014 Republican election wave. But with public opinion turning against Trump, even in Iowa, the first-term senator is in trouble too.
With five days until her Tuesday election, Ernst has regained her polling footing after a month of surveys giving Democratic challenger Theresa Greenfield a steady edge. The real estate executive still leads by an average of 1.8 percentage points, according to RealClearPolitics, but she doesn’t consistently reach that all-important 50% support threshold.
