Mr. Obama will propose cutting a variety of programs, including the Medicare Advantage subsidies for insurance companies that cover seniors who can otherwise acquire health coverage directly from the government. Another target is spending on private contractors, especially for defense, which spiked during the Bush administration. And he will scale back some promises, including his proposal to double money for foreign aid. Here what does the "defense" mean for? How did Bush deal with this probelm before? I'm confused. Thanks for reminding me.
