Correction: An earlier version of this story misstated the partisan breakdown of South Dakota’s congressional delegation. It is made up of two Republicans and one Democrat.
What goes around comes around. After losing virtually every toss-up Senate race in 2006, Republicans find themselves in prime position to pick up the four seats they need to control the Senate. And Democrats’ success five years ago means Republicans have plenty of targets from which to choose.

In this, the first installment of Hotline’s monthly Senate race rankings, we examine the seats most likely to change partisan control in next year’s elections. That is, we see Sen. Kent Conrad’s seat in North Dakota as more likely to wind up in Republican hands than Sen. Ben Nelson’s seat in Nebraska, and Sen. Scott Brown of Massachusetts more likely to lose to a Democrat than Nevada Sen. Dean Heller.
