Rick Santorum 
But our Rick isn't just releasing false and hypocritical attack ads - he's got plenty of other dirty tricks up his sleeve. For example, it was announced last week that he will enjoy a series of debates across Pennsylvania with Green party candidate Carl Romanelli. That would be Green party candidate Carl Romanelli who is entirely funded by Rick Santorum supporters, as noted in Idiots 254.
How convenient! That should certainly raise the profile of Romanelli - nowhere near close enough for him to win the election, of course, but certainly enough to siphon support away from Bob Casey. No wonder Santorum's supporters are donating to Romanelli in droves.
Bob Casey is quite rightly refusing to take part in this farce - his campaign spokesman Larry Smar said, "We have a rule that each campaign can only have one representative on stage for debate at the same time. As far as we're concerned, (Romanelli) is a representative of the Santorum campaign."
And Casey's refusal to participate has given Santorum's campaign another strawman to rail against - they're calling Casey weak because he won't play in Santorum's sandbox.
"Pennsylvania voters are fortunate to have two candidates for U.S. Senate - Rick Santorum and Carl Romanelli - who are not afraid to debate and stand up for their beliefs," wrote Virginia Davis, Santorum's press secretary, in an e-mail response. "It is unfortunate that the third candidate in this race, Bob Casey, either does not have beliefs or is afraid to stand up for them."
Which is a rather odd thing to say, because Santorum and Casey will be debating three more times before the election at official events which have already been arranged. So I guess the Santorum campaign is just making stuff up. Again.
UPDATE:
In googling, I found out that "On Monday, a state judge said Green Party candidate Carl Romanelli would be removed from the ballot because the party did not have enough valid signatures in its nominating petitions - a move pundits said would help Casey"
