The tight race reflects current party registration in Iowa — 33 percent Republican, 32 percent Democratic and 35 percent “no party,” he said

The poll found Clinton continues to struggle with trust issues. Among likely voters, 62 percent said she isn’t trustworthy and 9 percent weren’t sure. Trump was viewed as honest and trustworthy by 34 percent of respondents while 55 percent said he was not, with over 10 percent not sure.

Although the margin did not change in the four-way ballot test, Paleologos said the results suggest Stein and Johnson could have an impact in Iowa.

In conservative southwest Iowa, an area Trump likely needs to carry by a wide margin, Johnson polls higher than he does statewide — at 11 percent.

On the flip side, Stein’s numbers were higher with younger voters, a demographic that has shown less enthusiasm for Clinton. Among the 18-34 age group, Stein gets 9 percent — triple her statewide standing.

The most important issues to voters were jobs and the economy, 25 percent, and terrorism and national security, 21 percent. Choosing Supreme Court nominees, reducing the federal debt, health care and illegal immigration tallied 9, 7, 6 and 5 percent, respectively.
