The new Daily Kos/Research 2000 poll of the Pennsylvania Democratic Senate primary gives Rep. Joe Sestak a narrow lead over incumbent Dem Senator and ex-Republican Arlen Specter, with the election coming up this Tuesday.
The numbers: Sestak 45%, Specter 43%. The poll of likely Dem primary voters has a ±5% margin of error. Two months ago, Specter led by a healthy 51%-32% advantage. The TPM Poll Average now gives Sestak a lead of 44.3%-43.0% — the first time ever that Sestak has led in this measurement.
In addition, the poll has Republican former Rep. Pat Toomey leading Specter by 49%-41% in a general election, and leading Sestak by 45%-40%. The TPM Poll Average gives Toomey a lead over Specter of 45.6%-38.8%, and a lead over Sestak of 39.1%-35.4%.
