Final Analysis: The Democrats should pick up 2-6 seats, with the most likely number of pick-ups being 5 (which would mean that the GOP keeps control of the Senate). The key races to watch are Rhode Island, Missouri, Virginia, and Montana. Control of the Senate should swing on those four races and the Dems need to win all 4 to take control which would be difficult, but not impossible. If I absolutely had to make a pick in all four toss-up races, I’d say that the Democrat has a small edge in every one.

Hat tip to Real Clear Politics for the polling data.

Update #1: A change was made to a race on the list after it went live. Rhode Island was changed from leaning Democratic to toss-up.
