Who wants to be Secretary of Defense?

Washington (CNN) – One of the big guessing games around Washington, D.C., this holiday weekend is who is in, and who is out for the job of Secretary of Defense.

Since learning the White House pushed out Sec. Chuck Hagel last week, a growing list of possible replacements has emerged, with some candidates immediately taking themselves out of the running.

One prominent front runner, Sen. Jack Reed, D-Rhode Island, has already said, 'No, thanks.'

And now the scramble is on for a nominee.
