No, the cornfields are not full of dumb blondes (except when Fox News shows up), but it truly is hard not to be sexist in Iowa.
For example, I think it's reprehensible to take tens of millions of dollars from murderous kingdoms and dictatorships and then waive restrictions on selling them weapons including the weapons that Saudi Arabia has been using to slaughter men, women, and children in Yemen. And this makes me a sexist, or so I'm told.
In my view, parroting every war lie of Bush and Cheney was disgusting enough, but then pretending you meant well and didn't understand, even though once the war was begun you voted over and over again to fund it, is literally criminal as well as a moral abomination. Taking so many millions of dollars from war profiteers just makes it worse -- at least in the eyes of us sexist fans of Jill Stein.
