Don't know if it belongs in this thread and there is obviously no link, but Chuck Todd on MSNBC mentioned private internal polling from one of the party congressional committees that had "Clinton up 13 points" in one of the "swing districts in Iowa"
Iowa only has 4 congressional districts and 2 of them are swing districts (the 1st is Democratic and the 4th is Republican)
It's IA-2 that is typically democratic and IA-4 that's reliably republican. IA-1 is lean D so maybe he's talking about this district. A republican rep got elected in 2014 that had been held by a democrat, but it's likely to flip back this year. IA-3 is swing, maybe a tiny tilt R.
Either way if Clinton is truly up 13, whether it's IA-1 or 3, then she has the state.
