Now, where are the people who said this was likely R bodering safe R due to Ernst being a Strong IncumbentTM?
I'm willing to argue it was at the beginning of the cycle, but Ernst is blowing this race, and if Republicans are actually losing the NPV by 12 or 13 in November, I'd expect this seat to be hotly contested. Also Iowa is definitely a state that would wildly swing to the Democrats in a landslide, given its elasticity. It's kind of baffling to me how she's suddenly collapsed, but I guess national Democrats were on to something when they said they saw opportunity in this seat. Anyways, my guess is Ernst would win by 1 or 2 at the end of the day, but this race is now clearly a tossup, which is terrible news for Senate Republicans' hopes of holding the chamber (they need to win this seat and by a somewhat sizable margin to have any hopes of keeping the majority, especially given the partisan leans and demographics of the other battlegrounds (such as NC, GA, and AZ)).
