Sure, the state voted for Joni Ernst for the Senate last year --but she is terribly unpopular.
Can we ban this liar yet?

You are welcome to disagree with my interpretation. You can also accuse me of being a partisan hack. You are also welcome to explain why the poll is invalid or irrelevant, such as its age or that it comes too soon after an election (it is from April). But if I have a source, and the one thing that it shows is that I am no liar.
I see Chuck Grassley as unstoppable unless his health fails because his approval rating is consistently in the low 50s. Contrast the polls for Pat Toomey which go all over the map. He is the sort of politician who can win reelection in a swing state in a wave election for the other Party. Joni Ernst? I would definitely not say that ye, but 2020 is a long way off, is it not?
Because of the early caucuses in Iowa, and because until recently Republicans have gotten more attention, Republicans dominate the political discussion in Iowa.
Same is true for NH and yet Democrats are far ahead in the polls there.
New Hampshire and Iowa are very different states even if they are swing states.
