With three months to go, Rasmussen Reports polling shows that Republicans are poised to pick up Democratic-held Senate seats in three states— Arkansas, Indiana and North Dakota. Two others are leaning that way--Delaware and Pennsylvania. Arkansas' Blanche Lincoln is the only incumbent senator left in these races who is currently projected to lose a seat. The others are open-seat races following retirements by Democratic incumbents, with the exception of Pennsylvania, where incumbent Arlen Specter was defeated in the state's Democratic Primary.

At the moment, no Republican-held seats appear headed for the Democratic column.

Currently, there are six states in the Toss-Up category. Outside of the Toss-Ups, projections indicate that Democrats can probably count on having 49 Senate seats after Election Day, while Republicans will hold 45.

Five of the six Toss-up states are currently Democratic seats, while one is held by the GOP.
