Ohio Sen. Rob Portman has opened up a huge lead over former Gov. Ted Strickland with just two months until Election Day, according to a new poll.

According to the latest Bloomberg poll, Portman now leads Strickland by a whopping 17 points, 53-36, as Strickland has seen his poll numbers suffer over the past couple of weeks. It’s also the second poll in a week to show Portman up by double digits. A Quinnipiac poll last week showed Portman up by 11 points.
