The new Daily Kos/Research 2000 poll has Sen. Arlen Specter (D-Pa.) holding onto a lead in the Democratic primary against Rep. Joe Sestak (D-Pa.) and also leading Republican challenger Pat Toomey. Specter leads Toomey by 6 points, 47 to 41. That’s on the heels of a Quinnipiac poll that gave Specter a 7-point lead — although the polling average, which includes some incredibly good Toomey numbers, still shows the GOP candidate with a lead.
