Reasons for Warnock:
Major piece in turning Georgia into a swing state overnight
Georgia, again, turning quickly blue
The lack of political experience from Herschel Walker
Stacey Abrams will likely use another get out and vote message to Georgia democrats
How Walker could defeat Warnock:
Simple Reason, the party that wins the Presidency almost always has a bad midterm
Tons of very progressive statements made by Warnock as his time as a pastor
Walker could potentially attract black voters to him
The main reason Warnock won other than a terrible campaign from Loffeler was that by that point Trumps message of voter fraud had gone beserk and democrats took it to their advantage, and Walker is more moderate so he could basically attract republicans from most circles
