Much remains to be seen about this story, but a Casey internal poll claims to have the race narrowing to 47-44. Apparently, this poll was taken before the debate on MTP so it could be a bit closer. I have no problem if people don't take this number seriously, it could very well be a bit of pyops by the Santorum side. Still, I haven't heard Casey's people rebut the number. Could this be the beginning of another Casey collapse? Another week or two will tell us if this number is real. Still, I would have to say that the numbers have moved slowly towards the Republicans over the past few weeks. That's just my impression, not fact.
