The hangup right now that is preventing us from reducing the deficit is the Republicans. The Democrats have compromised. They've agreed to do domestic spending cuts they don't want to make. The Democrats are consistently proposing larger deficit reduction packages than the Republicans these days. But the Republicans are refusing to cut military spending or increase revenues. The are unwilling to address 2/3 of the problem and the Democrats aren't willing to just let them try to take it all out of the middle class.
The $4 trillion in deficit reduction Obama proposed and the $3 trillion the super committee Democrats proposed were both over 10 years.
