Republicans will win back the United States Senate, ending the Democrats' 8-year streak by picking up the following Senate seats:
1. South Dakota (Open)
2. West Virginia (Open)
3. Arkansas: I just see anti-incumbent sentiment dooming Pryor: backlash against the AR Dems is too strong (see GOPers taking out Lincoln in 2010, winning several down-ballot statewide offices that year and winning both chambers of the General Assembly in 2012).
4. North Carolina
5. Montana
6. Iowa (Open)
7. Michigan (Open): Snyder could have coattails to help Land cross the finish line
Snyder might have coattails to help Land, but that seems doubtful at this point. I'd say that Cassidy would defeat Landrieu in Louisiana and Gardner would defeat Udall in Colorado before Land wins.
