Republican Pat Toomey is pulling away in the race for Arlen Specter U.S. Senate seat from Pennsylvania.

From Rasmussen Reports:

Congressman Joe Sestak's post-primary bounce appears to be over, and he now trails Republican rival Pat Toomey by seven points in the U.S. Senate contest in Pennsylvania.

A new Rasmussen Reports telephone survey of Likely Voters in Pennsylvania shows Toomey with 45% support, while Sestak earns 38%. Five percent (5%) prefer another candidate in the race, and 12% are undecided.

Two weeks ago, just after his widely covered primary victory over longtime Senator Arlen Specter, Sestak posted a modest four-point lead lead over Toomey.

Prior to the primary, however, Toomey tended to enjoy modest leads over Sestak.
