Democrat Josh Turek leads Republican Rep. Ashley Hinson 48% to 45% among likely voters in Iowa's open Senate race, according to a Marist poll released October 15. In the race for governor, Democrat Rob Sand leads Republican Zach Lahn 52% to 45%.
Both results are within or near the poll's margin of error, but they put two Democrats ahead in a state that has trended firmly Republican for a decade.
What does the new Iowa poll show?
Marist surveyed 1,100 Iowa registered voters from October 8 to 11 by phone, text and online. The margin of error is ±4.5 points for registered voters and ±6.6 points for likely voters.
| Race | Democrat | Republican | Group |
|---|---|---|---|
| U.S. Senate | Turek 48% | Hinson 45% | Likely voters |
| U.S. Senate | Turek +7 | — | Registered voters |
| Governor | Sand 52% | Lahn 45% | Likely voters |
| Governor | Sand +11 | — | Registered voters |
| Generic House ballot | 47% | Republican 50% | Likely voters |
An earlier Fox News poll, taken June 23 to 27, had Turek ahead 50% to 46% among registered voters.
Why do voters still expect Hinson to win?
Even while backing Turek, Iowans are skeptical he can win. Fifty-nine percent of likely voters expect Hinson to be elected. In the governor's race, expectations are split: 50% think Sand will win and 45% think Lahn will.
The generic ballot shows why. Republicans lead 50% to 47% among likely voters on the question of which party's candidate they will support for the House, and 63% expect the Republican in their own district to win. Turek and Sand are running ahead of their party.
Who is driving the Democratic lead?
Independents. Among independent likely voters:
- Senate: Turek 51%, Hinson 31%
- Governor: Sand 67%, Lahn 26%
Marist also found a 29-point gender gap in the Senate race.
How is Trump affecting the race?
Trump's approval among Iowa likely voters is 44%, with 53% disapproving. Asked about the role he plays in their congressional vote, 44% said he is not much of a factor, more than one in three said their vote is against him, and 21% said it is for him.
The economy is a drag on the party in power. Forty-two percent of likely voters said their personal finances got worse over the past year; 36% said they stayed about the same and 20% said they improved.
Why does Iowa matter for Senate control?
Republicans hold 53 Senate seats, and Democrats need a net gain of four to win the majority. An open Republican seat in Iowa was not on most early lists of Democratic targets, so a competitive race there widens the map. Forbes now lists it among the closest Senate contests in the country, alongside races in Texas, Ohio, Maine and Kansas.
