Signaling Republicans’ continued momentum in key races, the Washington Post has moved both Wisconsin’s and Washington State’s Senate races from “Lean Democratic” to “Toss Up”:

• Washington (Move from Safe Democratic to Lean Democratic): Republicans recruited their best possible candidate in former state Senator and two-time gubernatorial nominee Dino Rossi. Polling suggests the race is close although Sen. Patty Murray (D) has been consistently underestimated throughout her career.

• Wisconsin (Move from Safe Democratic to Lean Democratic): The upper Midwest is bursting with Republican pickup opportunities this fall and Republicans recruited a credible candidate — wealthy businessman Ron Johnson — into the race against Sen. Russ Feingold (D).
