The latest Rasmussen poll has Republican Pat Toomey up 48-44 percent over Congressman Joe Sestak in the race to replace Arlen Specter as senator from Pennsylvania.
The poll taken Thursday night surveyed 750 likely voters and has a plus-minus of 4 percent. Seven percent of voters said they were undecided while 1 percent said they liked another candidate.
While unlike other recent polls it still showed Toomey with a lead it was the closest Rasmussen poll between the two since May.
The previous Rasmussen poll , taken Oct. 12, showed Toomey ahead 49-39 percent.
