Poll flux: Toomey back on top

When it comes to the Pennsylvania Senate race, it really depends upon whom you ask.

After a pair of polls showing Sen. Arlen Specter (D-Pa.) leading former Rep. Pat Toomey (R-Pa.) came out last week, a new one shows Toomey right back in the lead.

Susquehanna has Toomey ahead 42-36. The same poll in October had Specter up 42-41. The October poll tested registered voters, which has generally cast Specter in a better light, while the newer poll was conducted among likely voters.

Specter's primary opponent, Rep. Joe Sestak (D-Pa.), was not tested in either a Democratic primary or the general election, for some reason.
