Washington - One day after congressional elections, four races in the Senate remained undecided Wednesday and the outcome in a handful of contests in the House of Representatives were still uncertain.
But it was clear that Democrats had widened their majorities in both chambers.
Democrats capitalized on the backlash against Republicans and President George W Bush to pick up seats. The Democrats won three Senate seats vacated by retiring Republicans in Virginia, New Mexico and Colorado, while Democratic challengers ousted two of their Republican opponents in New Hampshire and North Carolina.
