Literally every Senate race in the country for 2024 will be Chuck Schumer vs. Mitch McConnell, same as the last several cycles. Doesn't matter how likeable they are, how they governed the state, any of that. A Manchin loss or retirement means 50-50 is all Democrats can realistically hope for, so I hope we're getting some old judges out of the way. If this and last year taught us anything, it's that the courts matter.
A 50-50 Senate without Manchin, Sinema, and Feinstein in it would be astronomically better than a 51-49 Senate including them.
