The Rothschild model published an updated prediction of the election outcome. It currently predicts a two-party vote share of 43.0% for Clinton and 0.0% for Trump in Iowa.
Iowa is traditionally a swing state, where the Democratic and Republican candidates have historically achieved similar levels of support among voters. This is why the election outcome here is considered important in determining who will win the majority of electoral votes.
Putting the results in context
