General Discussion

She over-performed in an R+22 district, coming within single digits of winning. She did that while being an unapologetic Progressive Democrat.
I honestly don't understand why so many are overtly hostile towards AOC and other progressive Democrats in general. AOC has been out there on national tours, building the Democratic base and filling every venue, everywhere they go.

AOC has nothing to do with the lose. It has everything to do with a deep red district that Republicans paid millions of dollars to win in a R+22 district that shouldn't have even required a real campaign. Ms. Behn did an amazing job and is in a good position to actually win the seat in November.
Bonus: every Republican, even those in R +10 or R +15 districts, just got a reality check that their seats are no longer safe. It was worth it. It will now force then to spend money they wouldn't have otherwise spent and force through RNC to pick and choose what seats they will spend money and effort to hold onto to given the change in mood of the electorate. They will turtle and they makes them vulnerable.
