Does anyone have any clue why Ernst’s popularity is eroding? It seems to have come completely out of nowhere.
She's always been a pretty weak incumbent coasting on state trends.* I've never understood why folks seemed to unironically think she was some sort of #UnbeatableTitan. It's one thing to say Iowa is trending Republican and that it's reached the point where she's probably safe despite being a weak incumbent. It's another to act like she's a strong candidate in her own right. Anyway, Lean R at this point.
*And in 2014, on the combination of 2014 being a Republican wave and the astonishing incompetence of her Democratic opponent, Bernard Bateman.
