There is another that is incorrect as well, as I was corrected myself two years ago, when I spelled it just has you have here.
I think you are are overemphasing the changes to the seat. It didn't shift all that much you know, as it was already R+6 before. Also, it is substanially the same territory, the non Buffalo parts of Erie, Wyoming, Genesse, Suburban Monroe, Livingston etc. The same media markets, the same voters for the most part. You don't get a "do-over" because of redistricting when the district is maybe 80%-85% same. Maybe 2 points or so.
Blame? Lol. It was her candidacy and her campaign. She ran it the way she thought best in a seat that has been in Republicans hands since Jack Kemp won it as a much more compact and more Democratic seat in 1970, that has been the best performing GOP seat in the state for the last decade, which had seen almost every other seat falter in bad times (Yeah Reynolds sucked in 2006, but that wasn't just his own campaign that was so. To think he coveted the Speakership at one point). I don't blame her for the loss, I credit her campaign with the results she achieved.
