My bet is on the former. This Senate seat assured Schumer would be majority leader in 2023. It was too important to lose. Walker did underperform vs. incumbent Governor Deal. Now whether that was due to country club weenies and soccer moms not liking Walker or the Democrats at the national perhaps not wanting Stacey Abrams is a question.
He ran into some family problems that also tripped him up. But he DID underperform Gov Kemp.
The same sort of situation occurred in Arizona, where the candidate was robbed.
