Ann Selzer is the best in the business and if she says Sen. Chuck Grassley (R-IA) is going to get his ninth term at 89, then he's going to get his ninth term at 89. Also worth noting, if Joe Biden runs in 2024 and Republicans say he is too old, Democrats who like the "whatabout game" could say "whatabout Grassley"?
As to Nevada, InsiderAdvantage has a noticeable Republican lean. Masto has actually led in five of the nine nonpartisan polls in October and was tied in one of the others. Don't take this one too seriously (V).
