Republican leaning swing states yes, but both states are swingy with a strong Democratic base that certainly could swing back in a Obama 12 size win.
I really think at this point, a 4-point Dem win probably does not carry Iowa and Ohio. Dems seem more likely to make further inroads in the suburbs than to move back toward Obama numbers in white working class areas.
Why do you think that? It's not the rhetoric of the party leadership at ALL right now, and they just saw it fail multiple times in a row.
