WASHINGTON: William Bennett and Mario Cuomo. Who could say "no" to this odd couple? The Partnership for a Drug-Free America hopes millions of teenagers will, after Congress says "yes." The political opposites are teaming up to take the helm of the Partnership, the organization that brought us those eggy "This is your brain on drugs" commercials. They'll be seeking $350 million from Congress and private sources to finance another Partnership anti-drug media blitz. That fits nicely with the White House's 1998 anti-drug strategy, which, coincidentally, also calls for a $350 million anti-drug advertising campaign, as long as private sources provide half the money. Where's Charlie Trie when you need him?
