On Monday we laid out five key counties to watch in Iowa for clues about the first GOP contest. Well, Trump ended up winning 98 of Iowa’s 99 counties, except for Johnson County, where Haley holds a one-vote lead, per the NBC News Decision Desk.
But underneath the surface, the margins help explain Trump’s decisive win in Iowa, and how DeSantis grabbed second place.
Here’s what happened in those five key counties:
Buena Vista County: Trump overwhelmingly carried this rural county in northwest Iowa, which is nearly 30% Latino, winning 62% of the vote while Haley and DeSantis each won 15%. DeSantis’ inability to run up his margins in a county Texas GOP Sen. Ted Cruz won in 2016 helps explain why he came in such a close second-place finish to Haley’s third place.
Linn County: Haley barely edged out DeSantis for second place in this eastern county, which includes the city of Cedar Rapids and its surrounding suburbs, winning 25% of the vote to DeSantis’ 24%, while Trump won 43%. That shows Trump underperforming compared to his statewide total, but his ability to win even suburban areas where he is less popular helps explain his wide statewide margin.
Polk County: The results in Polk County, the most populous in the state and includes Des Moines, help explain why Haley couldn’t overtake DeSantis for second place statewide. Polk was one of five counties Florida GOP Sen. Marco Rubio won in 2016, and the kind of higher-educated, suburban area where Haley’s campaign was looking to do well. But she came in third, with Trump winning 38% of the vote, while DeSantis won 27% and Haley won 26%.
Scott County: This eastern county, which includes Davenport, was another one to watch for whether Trump’s margin could be dragged down by anti-Trump voters in the suburbs. But that wasn’t the case. He won 49% of the vote here, similar to his share statewide, while DeSantis won 27% and Haley won 26%.
Sioux County: The results in this county in northwest Iowa also help explain how DeSantis was able to hold onto a second-place finish. He overperformed in this county, which is home to many evangelical voters, winning 31% of the vote while Haley won 26%. But Trump’s 45% vote share was still difficult to overcome, underscoring how Trump has solidified his support among evangelicals and Republicans in rural areas (he won just 11% of the vote there back in 2016.)
