Republicans would maintain control of Sen. Judd Gregg’s (R-N.H.) Senate seat if he is appointed Commerce secretary by President Barack Obama, Minority Leader Mitch McConnell (R-Ky.) said Sunday. “Sen. Gregg has assured me that if he accepts, it would not alter the makeup of the Senate in terms of the majority and minority,” McConnell said on CBS’ “Face the Nation.” Gregg, ranking member of the Budget Committee, could be named to Obama’s Cabinet as soon as Monday. If he does leave the Senate for the administration, Gregg’s replacement would be chosen by New Hampshire’s Democratic governor. McConnell maintained, however, that a Gregg replacement would still caucus with the Republicans. An administration official said Sunday that Gregg is the leading candidate for the Commerce job and could be named as early as Monday.
