Those approval ratings can't be right.
Why? I've yet to meet someone who has a nice word to say about our governor, and he's one of my favorite Democrats. Everyone just thinks he's doing an extremely poor job - basically an unmitigated disaster. Franklin & Marshall has him at an even worse 31%.
e: if the problem is with Toomey then maybe I could understand. I'm surprised that many people can answer the question about him. I don't think it's unrealistic for 7-8% to change their mind on him and cause the massive upward spike from an even split. It might be slightly too high but nothing egregious.
