Handel spent a good bit too - and far more of her $$$ came from groups (Super-Pacs and what not) OUTSIDE of her campaigns direct control:
About 2/3rds of Ossoff’s came from small contributions, compared to Handel’s 1/3rd. The GOPs donors tend to come more often from corporations (although that’s not insignificant in to democratic contributions, it’s just not as much). Plus, she won by 6% rather than either 9% (the percentage of GOP voters more than Democratic voters). Last time Price ran for the seat he won it by 20%. Clinton in 2016 actually WON part of the district (East Cobb, Newt’s old stomping grounds). This was barely a victory for the GOP. They might well lose the 6th next time, because people will remember why they disliked her in the first place, once she’s there in congress, I’m sure. She was not very popular as Sec. of State back in the day.
