They _believed_ in HRC. They couldn’t conceive of her not winning.
This guy in Georgia CD-06 is a nobody outsider attempting a straight-up election buy. Nobody “believes in him”, he’s just straight-up the most publicized candidate uttering the right drivel to the intended audience.
HRC was a way of life to her base.
Ossoff is a manufactured product the base is being told to buy.
Unfortunately, however, it was not by chance he chose to run in the 6th. With all the districts in GA apparently open to him, it was said elsewhere the 6th was the district where Hillary was the strongest.
