PPP also has Senate race tight, but with Murphy on top

An automated telephone survey by Public Policy Polling has a slightly different take than Quinnipiac University on the Connecticut Senate race: PPP has Democrat Chris Murphy with a 4-percentage point lead over Republican Linda McMahon.

In a poll released Tuesday, Quinnipiac had McMahon with a 3-point lead. The bottom line is the same: With two months until the election, the seat being vacated by the retirement of Sen. Joseph I. Lieberman is in play.
