White working class voters in Ohio and Iowa are trending Trump because of jobs and free trade. Despite that, they're still voting for Republican Senator Rob Portman, who is the biggest free-trader next to Paul Ryan in the entire Congress. They are probably fed up with the identity politics of the Democrats too; or they just like Trump's message.
Clinton should still campaign in Iowa, she can do well in Dubuque, Clinton, and Des Moines suburbs.
So you saying that Iowa is a better bet for Dems than OH???
I agree that there are many more undecided voters in IA vs OH, that tend to lean more Dem than Rep, but I believe that OH is still more winnable for Clinton *if* she can consolidate Obama voters in places like NorthEast-OH (Excluding Metro Cleveland), Toledo, Dayton, and bring Millennials back to the fold in Columbus and many other college communities throughout the state.
It might. She has to do well in the college towns and cities in Iowa.
