You know, I actually feel kind of bad for him, as he made the 2018 race with Stabenow much more competitive than it should have been, and in the 2020 race with Peters, he probably ran the better and more exciting campaign, and made the race the most competitive Senate Race in 2020, but he still lost, probably due to Biden carrying Peters over the finish line. However, I don't think he's the favorite against Whitmer at the moment, since she's the popular incumbent, but who knows?
Eh, the 2020 GA Regular Senate election was the closest Senate Race, and the most expensive Senate race in history.
