Wondering About Obama Tax Cuts?

Just passing this along with a hat tip to Wonk:

At ObamaTaxCut.com, they've got a tool you can use to calculate your family's tax cuts according to Senator Obama's proposals.

The numbers used all come from "the non-partisan Tax Policy Center," and the result is "the estimated difference between income taxes paid under George Bush's current policies and the the taxes under the Obama plan."

How long before Senator McCain's supporters produce one of these?
