For quite some time, Iowa was viewed as a swing state that usually leans Democratic. And its Democratic lean was never as evident as it was during the last two presidential elections, when Barack Obama was running for office.

That’s why Donald Trump’s blowout win there came as something of a shock. Yes, he had polled relatively well at times, but he was expected to squeak by, at best. In the end, he carried the state by a margin (9.4 points) larger than Hillary Clinton’s win in New Mexico (8.3 points), Virginia (5.4 points), or Colorado (4.9 points), and nearly as large as her win in Oregon (11 points).
