He has ranked the senate this week b/c of all the repubs retirements. All 4 retirements are in swing states that dems have been winning. Ohio, Florida, Kansas, and Missouri.
In this round, he makes an important point about these retirements. Even if we don't win them in the next election, it will cost the repubs a ton of money to keep them. That is critical in keeping the majorities we already have. And hopefully expanding on others. He says
Not only will GOP strategists have to spend considerable time and money (Florida, Ohio and Missouri are all expensive/very expensive states in which to advertise) to hold the seats but those expenditures are dollars that can't be spent on offensive opportunities in Colorado, Nevada and Illinois among other states.
I totally agree.
Check out his analysis of future, hopefully, dem victories in the senate.
