OH(Ryan-D) and FL(Demings-D) are Tilt/Lean R column.

How would he(Feingold) have done?
2012 was open seat to replace Kohl-D.
Obama/Biden-D won the popular vote in WI in 2012.
Feingold would have won re-election in 2012.

Feingold did not have to wait til 2016.
Baldwin-D or Kind-D could have challenged Johnson-R in 2016.

Sinema loses in the primary.

To make Sinema-AZ and Manchin-WV irrevelant,
PA(Fetterman-D) and WI(Barnes-D)
Manchin(WV) loses in the general election in 2024.
Sinema(AZ) loses in the primary election in 2024(unsure whether the seats stays Democratic.)
Democrats need to win NC(Beasley-D) to make it easier for Democrats to defeat NC(Tillis-R) in 2026(Erica Smith-D/ NC) and OH(Ryan-D) to make it easy for Brown(D-OH) to get re-elected.
