On the final Friday of Election 2006, Democrats take the lead for the first time in the race for control of the U.S. Senate. Today, Rasmussen Reports is switching two states (New Jersey and Montana from “Toss-Up” to “Leans Democrat”). We now rate 49 Senate seats as Democrat or Leans Democrat, 48 seats as Republican or Leans Republican and three as Toss-Ups. We polled in each of the Toss-Up States (Tennessee, Missouri and Virginia) on Thursday night and this may lead to further shifts in the Senate Balance of Power ratings.
