EDIT: Oh, and couldn't deficit increases be curbed by a reduced budget? A low tax rate would eliminate the need to spend a lot of money in certain areas (that the government spends a lot of money on right now). But of course, nobody likes to reduce the budget.
Wow, reduce the deficit by making the government less efficient without hurting anybody, nobody ever had that idea before...
We've had people committed to this idea setting policy in this country for 30 years now. All the low hanging fruit was plucked long, long ago. If you want to actually make the government more efficient you need to do some sort of major reform like nationalizing the healthcare system to control costs.
Here is a handy graph that gives you a look at what you are talking about trimming. Note that non-defense discretionary spending is only 530 billion... compared to a 1000 billion dollar deficit.

1) They will completely cancel a huge part of the federal government like disbanding the military or ending social security
2) They don't know what they are talking about
3) They are lying
