A certain cliche grabbed Mitt Romney's coattails last night.
From Newser: "Did you hear it? The sound of the fat lady singing as Mitt Romney swept Wisconsin, Maryland, and DC last night? These pundits sure did."
From The Washington Post: "That sound you hear? It’s the fat lady singing."
From ABC: "It is done. Fini. The fat lady has sung."
From Joe Scarborough: "Regardless, the fat lady has sung."
