I actually felt bad for Paul Ryan in last night debate as if a little boy was getting his ass whipped by his parents. Joe Biden appeared to be teaching his son some maths. “It’s mathematically impossible,” he responded to Romney-Ryan’s five-trillion-dollar income-tax cut. When Martha Raddatz pressed Ryan for specifics of how he could pay for his tax cuts, Ryan couldn’t give one. Mad props to Ms. Raddatz for an outstanding job of moderating the debate.
