Daily Kos: Beating Republicans at Their Own Game:

the game Republicans play when they try to force Democrats to get exceedingly specific on funding new or proposed programs, only to bludgeon the electorate with the screaming sound byte of Taxes will go through the roof!! Vote Republican or go broke!!

There's a simple way to respond for these gotcha games of details. When asked where money for proposed programs will come from, Democrats need to go ahead and say, We don't know. And the reason we don't know is because the cesspool of lies, secrecy, corruption and overspending is so rampant in Republican-run Washington that nobody has a clue about the real state of our fiscal affairs.
