Inside Washington

To help embattled Democrats plan for this year's campaign, STAN GREENBERG, President Clinton's pollster, studied congressional races in four so-called swing districts. In each, a Democratic incumbent faces a tough challenge because the districts have conservative leanings and tend to swing between the parties. The good news: Greenberg's research showed that the Democrats could pull out wins if positioned correctly. The bad news: the data also showed that in three of the four districts, Clinton would lose to Bob Dole.
