The news just keeps getting better on the polling front -- not just the USA Today poll reported yesterday, but for all polls:

A Capitol Hill sex scandal has reinforced public doubts about Republican leadership and pushed Democrats to a huge lead in the race for control of Congress four weeks before Election Day, the latest USA TODAY/Gallup Poll shows.

Democrats had a 23-point lead over Republicans in every group of people questioned — likely voters, registered voters and adults — on which party's House candidate would get their vote. That's double the lead Republicans had a month before they seized control of Congress in 1994 and the Democrats' largest advantage among registered voters since 1978.

Nearly three in 10 registered voters said their representative doesn't deserve re-election — the highest level since 1994. President Bush's approval rating was 37% in the new poll, down from 44% in a Sept. 15-17 poll. And for the first time since the question was asked in 2002, Democrats did better than Republicans on who would best handle terrorism, 46%-41%.

"It's hard to see how the climate is going to shift dramatically between now and Election Day," said John Pitney, a former GOP aide on Capitol Hill who now teaches at Claremont-McKenna College in California.
