There are seven seats that could switch party control this year. At this point, I see the Democrats possibly picking up five seats and the Republicans two. That’s a net gain of three seats for the Democrats, bumping their majority up to 56.
That’s still not enough to overcome a Republican filibuster, and it’s too early to be confident in these predictions.
The states up for grabs are Maine, Connecticut, Indiana, Massachusetts, North Dakota, Nebraska and Montana.
