This particular poll has a tell that leads me to think it is a bit more honest than most. It shows Sen. Grassley with a 15-point lead over the Dem challenger. He’ll likely win by 25 or more points, so this poll at least leans in the right direction.
i think this might be a little high based on what I see here in Iowa. iI do think Trump and Grassley win but it will be closer than these margins.
