Well this has been one heck of a couple of years for the Republican Party. Never in my life time have I see anything like it — given that’s a relatively short lifetime, but who’s counting?

And now that we’re headed towards the next big election, we wanted to get a better sense of what parts of Iowa would be the most likely to back Donald Trump again.

Specifically, which cities have the highest number of conservative voters in the Hawkeye State?

In order to do so, we turned our sites on measuring how each city in Iowa with populations greater than 5,000 voted and contributed to political campaigns in the past several years. The cities with the highest percentage of voters who voted republican and gave the most to conservatives where named the most conservative cities in the state.

Here are the 10 most conservative places in Iowa for 2019:

  1. Sioux Center (Photos)
  2. Orange City (Photos)
  3. Sheldon
  4. Le Mars (Photos)
  5. Oskaloosa (Photos)
  6. Clarinda (Photos)
  7. Spencer (Photos)
  8. Red Oak (Photos)
  9. Cherokee
  10. Atlantic (Photos)

If you’re wondering, North Liberty is the most liberal city in Iowa of all those we measured.

And to be clear, we didn’t form this list based on our own biases — we relied on the cold hard data. For more on how we ran the numbers, keep on reading. Then we’ll take a closer look at each of our top 10 most conservative cities in Iowa.

How we determined the most conservative cities in Iowa for 2019

We started by making a list of every city in Iowa over 5,000 people based on the 2013-2017 American Community Survey (The most recent data). That left us with 79 cities and towns.

We then measured the voting record and donation data to determine which places lean the most rightward in their allegiances by:

  1. Percentage Of Registered Republicans
  2. # Of Contributions To Republicans Per Capita
  3. $ Amount Contributed To Republicans Per Capita

Next, we ranked each city from 1 to 79 for each of the criteria where number one was the most conservative.

The winner, Sioux Center, is “The Most Conservative City in Iowa For 2019”.

Let’s go through these conservative places, shall we?
