Colorado and Iowa look like barn-burners, but other Republican targets are slipping down the priority list.

Rep. Gary Peters (D-Mich.) has opened a steady lead over former Michigan Secretary of State Terri Lynn Land (R) and Sen. Scott Brown’s (R-Mass.) campaign hasn’t taken off against Sen. Jeanne Shaheen (D-N.H.) in the way Republicans had hoped. The GOP still mentions Oregon, Virginia, and Minnesota as possible opportunities, but Democrats appear to be comfortably ahead in those states.

Democrats are upbeat about Georgia, where charity executive Michelle Nunn (D) has impressed. Businessman David Perdue (R) just won the GOP nomination after a protracted runoff, but Democrats believe they can pick apart his business record. Most recent public polling has found Nunn ahead in the race, though many of those same pollsters missed in the primary. Perdue likely has a slight edge.

Democrats also think the race against Senate Minority Leader Mitch McConnell (R-Ky.) will be close, though Republicans scoff at the idea that Kentucky Secretary of State Alison Lundergan Grimes (D) can win.
