That’s the White House strategy on Bolton, according to the Washington Post. This passage suggests the WH is on the right track generally:

The White House is providing detailed rebuttals to any allegations Republican senators find troubling. Bush is also looking to make the debate over Bolton about reforming the United Nations, not Bolton’s temperament, and working with Senate Republicans to produce a vote count this week showing there are enough votes to approve the nominee on the floor.
A “nose count that demonstrates majority support for Bolton ensures that any Democratic effort to drag heels again in committee is just struggling against the inevitable,” said a senior Senate GOP aide. This marks the first time the GOP has threatened to circumvent opposition to Bolton on the Foreign Relations Committee, which would lessen the impact of having one or more Republicans on the panel oppose Bolton.
