Just like Santorum -- only without the bestiality (as far as we know)

It's common knowledge that Charles Schumer, who was also allegedly instrumental in getting Paul Hackett out of the Ohio Senate race, is also the architect of the Bob Casey, Jr. candidacy for the Senate Seat now occupied by Rick "Man on Dog Sex" Santorum.

Here are the two candidates on the issues:

Rick Santorum (Republican)
On abortion -- pro-life
On stem cell research -- opposed
Accepts PAC money -- yes
War in Iraq -- it was the right thing to do
Troops in Iraq -- stay the course
National Health Care -- opposed
Raising the minimum wage -- supports an increase of $1.10
NAFTA/CAFTA -- supports CAFTA; opposed NAFTA
Alito confirmation to Supreme Court -- supports confirmation

Bob Casey, Jr. (Democrat)
On abortion -- pro-lfe
On stem cell research -- opposed
Accepts PAC money -- yes
War in Iraq -- supported
Troops in Iraq -- stay the course
National Health Care -- opposed
Raising the minimum wage -- supports
NAFTA/CAFTA -- opposed both
Alito confirmation to Supreme Court -- supports confirmation

So aside from the fact that Bob Casey isn't obsessed with fucking the family dog and presumably doesn't bring dead newborn siblings home to the kids as a new toy, would someone please tell me what the difference between these two numbnuts is?
