Poll: Most Iowa voters want Sen. Chuck Grassley out

The majority of likely Iowa voters say it's time for someone new to take over Sen. Chuck Grassley's seat, according to the latest Des Moines Register/Mediacom Iowa Poll.

Why it matters: Grassley's seat has been viewed as so invincible in the past, electability polls haven't been conducted prior to an election cycle, said J. Ann Selzer, who ran the Iowa Poll.

• But Iowa's reliably red seat now appears "vincible," Selzer said.

By the numbers: 64% of likely voters said they believe someone new should hold Grassley's seat.

• 37% of those are Republicans, 89% Democrats and 68% are independents.

Yes, but: If Grassley decides to run again, he will still hold a strong advantage over any competitor because of his name recognition and long incumbency.

• 27% of likely voters said they would reelect Grassley — the majority (51%) of whom are Republicans.

Between the lines: Though the 87-year-old senator is a household name, there's growing sentiment that Iowa's longest-serving has been in office long enough.

What they're saying: "He still does care about the people and the farmers," Dawn Leiser, a 46-year-old independent, told the Register. "It's just that we need to get fresher and newer blood unfortunately."

Methodology: 630 likely voters were polled about the 2022 midterm elections from June 13-16. The poll's margin of error is plus or minus 3.9 percentage points.
