While I actually can vote for either Casey or Santorum, I have a feeling that Santorum will pull this off. His ads are better than Casey' and so far Casey just hasn't done anything to generate support that I can see. Since political alternatives have been banned this year in the People's Republic of Pennsylvania I can either (a) stay home (b) vote Casey or (c) vote Santorum. Hmmm door number ....
Leading in every poll and having all of the major political scientists and pundits might be evidence that he has done something to generate support.
