Since then, it has become far more of a swing county, having backed the national winner in the seven presidential elections from 1992 to 2016. That streak was broken in 2020, when Donald Trump won the county but lost nationally. The county is considered a bellwether polity.[15]United States presidential election results for Marshall County, Iowa[16]YearRepublicanDemocraticThird partyNo.\u202f%No.\u202f%No.\u202f%20209,57152.77%8,17645.08%3892.14%20169,14650.87%7,65242.56%1,1826.57%20128,47244.44%10,25753.80%3351.76%20088,27844.36%10,02353.71%3621.94%20049,55749.87%9,44349.27%1640.86%20008,78549.85%8,32247.22%5172.93%19967,01740.50%8,66950.04%1,6389.46%19926,78437.09%8,30345.40%3,20217.51%19887,65743.63%9,76055.62%1320.75%198410,83954.63%8,80944.40%1920.97%198010,70754.56%7,11436.25%1,8059.20%19769,56251.33%8,69546.67%3732.00%197210,79860.85%6,61837.30%3281.85%19689,40256.35%6,36238.13%9225.53%19646,32339.09%9,81560.68%380.23%196010,26560.23%6,76139.67%160.09%195610,30562.74%5,75535.04%3652.22%195211,13565.93%5,31431.46%4412.61%19486,69852.19%5,60243.65%5334.15%19447,32555.67%5,59842.55%2341.78%19408,50356.44%6,49743.13%650.43%19367,37752.66%6,29744.95%3342.38%19326,60448.98%6,38547.36%4943.66%19289,32672.90%3,38426.45%820.64%19249,01068.09%1,51611.46%2,70720.46%19209,33479.10%2,16618.36%3002.54%19164,17260.32%2,41434.90%3304.77%191292613.79%2,16232.19%3,62954.03%19083,88761.34%1,94130.63%5098.03%19044,22966.74%1,20318.98%90514.28%19004,87865.07%2,32931.07%2893.86%18964,54161.85%2,62635.77%1752.38%See also[edit]References[edit]^ a b c “2020 Census State Redistricting Data”. census.gov.
