Like my colleague Derek, I played with the New York Times deficit calculator, and this is what I came up with: allowing the Bush tax cuts to expire, eliminating or modifying major tax subsidies like the employer health insurance deduction, and cutting all manner of subsidies. I could have gone farther, but I deliberately left most military spending alone--not because I think it shouldn't be cut, but because I have absolutely no idea how many ships the US should have, or what the consequences would be of cutting their number. On the other hand, I'm relatively comfortable with my grasp of what would happen if we eliminated farm subsidies.
Save your eyes. Take breaks.
