I hope Arlen sits this one out.
He only cares about himself so it's expected that he'll do little for Santorum. He can't totally sit it out. This is another reason why Santorum was just plain wrong for backing the RINO over Toomey.
Wow! Phil, my respect for you has been restored. I didn't think you would ever say this about your political hero! (BTW, I had a political hero once... a Governor of Michigan and a Michigan Supreme Court Justice after that... he ended up going to prison later in life. Political heroes can be disappointing at times!)
