Rove is obviously greenlighting a pre-emptive attack on Hagel via noise machine rag Human Events. The give away is the last sentence.

White House Fears GOP Senator Will Kill Bolton Nomination
Human Events has learned that the White House has become increasingly nervous about the confirmation of John Bolton to be U.S. Ambassador to the United Nations.
As a new week begins on Capitol Hill, conservatives are beginning to worry that the Democrats' smear campaign against John Bolton might be working.
Liberal GOP Sen. Lincoln Chafee (R.I.) has long been a question mark for the Senate leadership. Now Majority Leader Frist must add fellow presidential hopeful Sen. Chuck Hagel (R.-Neb.) to his list of possible turncoats.
Sources say that the White House is taking seriously reports that Hagel is considering a vote against the President's pick to represent the U.S. at the United Nations in committee.
Conservatives in Washington believe that, in effect, a vote against Bolton would put an end to any hopes for higher political office that Sen. Hagel may harbor.
