PUT THEM ON COMMISSION!
Give each Congressman $1,000 TAX FREE dollars for each billion they all agree to cut. Ditto Obama. They can keep it or use it for campaign spending or give it to charity.
If they cut $400 BILLION from next year's budget that would earn them each $400,000 bucks - tax free, Multiply this by the number of years they save it, but pay it out year-by-year.
Oh yeah, there's this too: don't pay them a penny if they don't make the cuts!
(UPDATE; FOR $400 BILLION/YEAR IN SAVINGS, IT WOULD ONLY COST $215 MILLION/YEAR.)
