The Metrics that this Channel is using seem reasonable to me.
https://docs.google.com/spreadsheets/d/17GB1uLv4tEwojwz5GXmvzG0f5fjfk1b3Q1cTbGB5CHo/edit#gid=111764548RACE 1Senator Raphael Warnock (D, Incumbent) vs Herschel Walker (R)
https://www.youtube.com/watch?v=fgYJYfGNq1sEPO predicts it will go to a Runoff. However 4,575,000 Total Votes seem a bit too high for me.
GA had one of the strongest Turnouts in 2018 in a Non-Presidential Year with 3,9M+ Votes and he is saying the State will exceed their 2018 Turnout. I don't think so.
Next Race: INDIANA (Todd Young, R vs Tom McDermott, D)
Chime in here if you have thoughts!
