If President Obama nominates Senator Clinton to serve as Secretary of State, it presents an interesting problem for the Republicans. Unless I’m mistaken, this will be the first time they have had a chance to gather her testimony under oath. Some Republicans will probably suggest that they should let bygones be bygones. That might be wise, but it might also make sense to pull out the entire Clinton file and ask Mrs. Clinton about the Rose Law firm billing records, her insight into the cattle futures market, etc.? After all, Senator Obama promised to change the tone in Washington. That promise implied getting away from the Clintonian way. If the leaks about his cabinet and White House staff are correct, that’s not what he’s doing. In the case of Mrs. Clinton, the Republican party might be able to bring that up in a way they can’t in other cases. An interesting question, in my book.
