The payroll tax cut benefits the majority of people, especially the middle class. The tax cuts that were the big issue in the supercommittee were the ones primarily for those who make millions. If a person opposes one in the name of not raising taxes, doesn't a person have to oppose the other for the same reason?
It's legitimate to oppose raising one and not the other for economic reasons (and this argument has been used for not raising on both ends of the wealth spectrum). You might think one or the other cut benefits the economy more. But if your argument is not raising taxes, then there's something else driving your position, something you're not owning up to.
