You know, if any canidate, GOP, Dem, or Tea-Partyer came flat out and said "I will balence the budget by cutting exactly X% of [Insert govt service] and I will do that by doing this, this, and this", I would seriously consider voting for them.
As would I. What's officially counted as pork and all the "waste, fraud, and abuse" makes up such a small portion of yearly outlays that it's akin to asking your average household to cut out one soft drink a week to balance their budget.
Those numbers (such as the $500 B in "waste, fraud, and abuse" that got tossed around before all the Democrats were attacked for cutting Medicare) are only that large because they're mutliplied over ten years. Fifty billion per year in a yearly budget topping three trillion isn't much.
