Democrats appear likely to have a net gain of four seats and regain control of the U.S. Senate though the large number of toss up seats make that likelihood far from certain. The Dakotas, where Democrats held an edge in both during September, have denied the Democrats a certain capture of the Senate though the uncertainty in Colorado, and over the re-election of Sen. Cranston in California also contributes to the doubts. If you assume that Democrats lose two of their four vulnerable seats, they then must pick up six Republican seats. Maryland, Nevada and Florida now look almost certainly headed for the Democratic column but three more are needed from the remaining seven GOP toss up seats. At this writing, the two most likely seats from that seven to drop would be Idaho, North Carolina and perhaps South Dakota, though polls differ greatly on who is ahead in South Dakota (each party's polls has their candidate up by four or five points).
