Another Pennsylvania Poll Shows a Double-Digit Obama Lead

John McCain senses an opening in Pennsylvania, and he is working hard to exploit it. It must be troubling for McCain, what his internal polls may be telling him, that one public pollster and after another has seen a formidable Obama lead in the Keystone State. This morning comes a new poll by Franklin & Marsh/Daily News that suggests the senator from Illinois enjoys a 13-point advantage among likely voters over the senator from Arizona:

Obama 53
McCain 40

Obama's advantage among voters in Pennsylvania is nearly twice what it was in September.
