It’s certainly possible that one or both of these nominations could stall on Capitol Hill. Mr. Hagel, in particular, looks headed for a tough fight. But both nominees can take some comfort in historical numbers. Traditionally, the Senate gives presidents more leeway on executive-branch appointments than it does on Supreme Court picks, on the theory that they are not lifetime appointments and that the president needs to work with people he can trust. Senators block cabinet nominees about 2 percent of the time.
Since World War II, the Senate has actually voted down only two such picks, according to the Senate Historical Office.
The first of these was President Dwight Eisenhower’s 1959 choice to lead the Department of Commerce, Lewis Strauss. A former admiral, Strauss had accumulated many enemies as the outspoken head of the Atomic Energy Commission. His confirmation hearing did not go well, as he gave what some senators considered evasive answers while demanding to cross-examine hostile witnesses. In addition, Democrats had made big gains in both House and Senate in the 1958 mid-term elections, and held a 64-to-34 Senate majority.
