Another anecdotal indication that this will be a big wave; The DCCC is putting money into PA's 12th district to support Summer Lee, after assuming she was safe. This is a district that has has a Democrat for almost 30 years and voted for Biden by 20%.
AIPAC, which spent $3mm to try to defeat her in the primary, has also started spending again, their first general election spending.
Hopefully the Jewish community in Pitts can learn from Cleveland...
