A new poll has former President Donald Trump leading the Republican field, by a lot, in Iowa. 

The poll was conducted by National Research Inc. on behalf of American Greatness.

The pollster surveyed 500 'likely Iowa Republican Primary voters" during a two-day period from July 5 to July 6, 2023. The margin of error is plus or minus 4.38 percentage points.

The margin of error, however, does not really come into play because the poll easily puts Trump on top of the Republicans' 2024 presidential field in Iowa.

Trump continues to dominate

In the poll, Trump received 44% of the vote, which puts him back where he was in May, after a brief drop to 39% in June.

As with many other polls, this poll has Florida Gov. Ron DeSantis as Trump's chief Republican rival. DeSantis came in second place with 21% of the vote - which is 23 percentage points behind Trump. And, in contrast to Trump, DeSantis's numbers have only been going down, from 26% in May to 24% in June and now to 21% in July.

After Trump and DeSanits, the next most popular choice among Iowa Republican Primary voters is "undecided," which received 14% of the vote. There is then a slew of candidates below 10%.

As would be expected with numbers such as these, the pollster found that Iowa Republican Primary voters prefer Trump over DeSantis on virtually all of the major issues.

The pollster also made one other, perhaps, significant finding. Per American Greatness:

DeSantis is losing among voters who have a favorable impression of him. Twenty-eight percent of these folks say DeSantis is their preferred candidate while 42% chose Trump. Voters who have a favorable impression of both men chose Trump as well, 55% to DeSantis’s 25%.

The fight for Iowa

Former President Trump made a campaign stop in Council Bluffs, Iowa on Friday. This was just after National Research Inc. released its results.

There, Trump referred to himself as "the most pro-farmer president that you’ve ever had," and he said that he "fought for Iowa ethanol like no president in history."

Trump, during his speech, also took a few shots at DeSantis. Trump said:

He would be a catastrophe for farmers of Nebraska and Iowa and anyplace else. DeSanctus, as I call him, the abbreviation [for DeSanctimonious], is a globalist sellout, a Paul Ryan and Karl Rove acolyte who is in the pocket of Wall Street donors at the Club for No Growth.

Trump further claimed that "Ron DeSanctus totally despises Iowa ethanol and ethanol generally," saying DeSantis has "been fighting it for years." Trump added, "Don’t forget, as a congressman he was voting against it, and fighting for years to kill every single job."

The remarks provoked a response from DeSantis 2024 campaign, which put out a statement, saying, "As president, Ron DeSantis will be a champion for farmers and use every tool available to open new markets."
