Possible common ground in budget aftermath: Defense spending, public works, corporate taxes

Some of the proposals in President Barack Obama's new budget address major concerns of the Republican-controlled Congress.

Obama and Republicans could find common ground on proposals to increase defense spending, upgrade the nation's aging infrastructure and fix the corporate tax system.

Full agreement on any one of those is still a long shot. There are significant differences between Obama and Republicans over scale and scope in each of their intersecting interests.

How far apart could begin to become evident Tuesday when Treasury Secretary Jack Lew and White House budget office director Shaun Donovan testify before key congressional committees about the president's budget.
