Poll: Democratic candidates open large lead in congressional races

Four weeks before congressional elections, a new USA TODAY/Gallup Poll shows Democrats hold a 23-point lead over GOP candidates. That's double the lead Republicans had a month before they seized control of Congress in 1994.

President Bush's approval rating was 37%, down from 44% in a Sept. 15-17 poll. The approval rating for Congress was 24%, down 5 points from last month.
