From America's Newspaper of Record this morning (page 5, can't find it online):
[Romney] didn't even touch Joe Biden's blunder yesterday about the middle class being "buried" over the last four years.
Did so. Eleven percent of the way down this transcript (oh, just do a page search on "buried"):
Under the president's policies, middle-income Americans have been buried. They're just being crushed.
Deft and sly. Nice to know Romney has it in him.
