lone walk
n.— «Current Governor and 2008 Republican Hopeful Mitt Romney will not be on hand for the festivities nor will he, as Massachusetts Governors for generations past have done, do what is known as the “lone walk” where after he hands over the state to Deval Patrick, he leaves the State House one last time, by himself and walks away from his office.» —“Mitt Romney: Coward Or Racist?” by James Boyce Huffinton Post Dec. 22, 2006.
