For the second time in two weeks, a Newsweek poll is showing John Kerry beating President Bush.
Among registered voters, the Kerry-Bush matchup has Kerry winning over Bush 48 percent to 46 percent. Last week, it was 49 percent to 46 percent. However, because both of these outcomes are within the margin of error of three percentage points, it's a statistical dead-heat.
Bush would have clear wins over the other Democrats, Howard Dean, John Edwards, Wesley Clark and Joseph Lieberman. But the president's approval rating has now dropped under 50 percent in the Newsweek poll. His 49 percent is the lowest so far in that survey.
Meantime, Kerry is widening his lead over his Democratic rivals. He places first with 45 percent. That's more than three times more support than his closest contender, Howard Dean, who garnered 14 percent.
