While a whole heck of a lot of these may wind up being "competitive," there is no conceivable scenario where Democrats can seriously invest in all 12 of these races.
Agreed.
Agreed.
But in all honesty, people who say "Musgrove doesn't have any chance of making this close" are setting themselves up in rather more ridiculous fashion than people who are saying "he'll actually win".
I don't doubt that an open seat race in Mississippi will be
close, or at least much closer than we're used to seeing in the state. (Just like I don't doubt that Massachusetts will be much closer than we're used to seeing this year, either.) I just doubt that Democrats will be able to win a national race there statewide, regardless of the climate.
