Iowa and most of the states will go for Trump. In 2016, more than 200 counties flipped from supporting President Barack Obama in 2012 to backing Trump in the 2016 election. Iowa is home to 31 of the counties. But none compare to Howard County in Northern Iowa - it was the single largest pivot county in the country, flipping by 41 percentage points. Some who voted for Barack Obama twice and for Donald Trump in 2016. I would be unlikely for them to vote for a Democrat in 2020?
The big question is what Dem will get the majority vote today.
