[French; lit. to the fact.] Mr. McCain has delayed the formal announcement of his presidential bid until the end of the month. He is making room for three “major” policy speeches, and is revamping his fund-raising apparatus to make it more like the Bush machine that crushed him in the 2000 presidential campaign. He has also maderoom for a “blogger conference call,” to give the impression that he is both accessible and au fait with modern technology. (Economist, “The Comeback Grandpa?” 4/14/2007.)
