Sen. Arlen Specter (D-Pa.) continues to see his poll numbers decline, with just 23 percent of voters in a new poll saying he deserves reelection.

Specter has also seen his edge over Rep. Joe Sestak (D-Pa.) decline significantly, from 26 points in August to 12 points now, according to the Franklin and Marshall poll.

The poll shows 66 percent of voters saying it's time to elect someone else and has Specter at just 30 percent in the primary. Specter leads Sestak 30-18, after leading him 37-11 in an August Franklin and Marshall poll.

Specter is virtually tied with former Rep. Pat Toomey (R-Pa.) in the general election, leading 33-31. Toomey would lead Sestak 28-20.

Before Specter's party switch, 40 percent of voters in the same poll said he deserved reelection, while 46 percent said it was time for someone else. His reelect was at 34 percent in August.

The decline in his reelect numbers tracks closely with a Susquehanna poll from earlier this month, which showed it at 31 and dropping.

Also, Specter's job approval is at its lowest point in the 18-year history of the poll, at 29 percent positive and 64 percent negative.
