No, most of the Gov race and Senate races coincide with each other in 2022 and most of the 2016 Dem class are in Dem Gov states, that arent term limited except for Wolf in PA and Sestak can run for Senate at the same time Fetterman runs for Gov. Wi open seat is in WI, where Evers isnt term limited. Although, 2024 is less favorable, OH with Sherrod Brown and Ojeda running for Manchin can vote Dem in a Dem reelection
