Yeah, I didn't want to admit it, but Iowa is not going back to the Democrats this election. No polls so far have shown any indication of it, and this firm is pretty friendly towards the party. The anger of farmers towards the GOP is seemingly gone and the state should start to consistently vote Republicans in, if trends are any good indication.
PPP has so far been in line with many other polls for many other states. This nonsense about them being a "Dem friendly pollster" is not based in reality.
