I never said that Hill is finished. Quite the contrary, I said that she could easily make up a 2-point deficit by November (if the poll is accurate.) I was just disappointed to see the poll trend so sharply away from her after she was up by 7 with more than half of all responses in. One thing I am curious about is the implications of IA-01 being so lopsided. While it is one poll, if Blum really is losing by this much, could similar districts in the Midwest end up being more favorable for the Democrats than we're expecting? This races don't all happen in a vacuum.
It is certainly true that each race doesn't happen in a vacuum and to some degree you can infer things about similar districts from a result in one district, but Blum is also an especially weak incumbent who is a very poor fit for his district.
What basis do you have to say that? Blum outran Trump substantially in 2016... he won by 8 while Trump won his district by 4. And Trump did fantastically well in Iowa, so those are some darn good numbers for Blum.
