UPDATE, WED 8 PM: It's going to be a Democratic-led Congress.
Democrats have taken control of the Senate from Republicans with an upset victory in Virginia.
Jim Webb's squeaker win over incumbent George Allen gives Democrats their 51st seat in the Senate, and the Democratic Party complete domination of Capitol Hill for the first time since 1994.
The new Associated Press count shows Webb with more than 7,200 more votes than Allen. Virginia has had two statewide vote recounts in modern history, but both resulted in vote changes of no more than a few hundred votes.
The astonishing turnabout comes at the hands of voters unhappy with Republican scandals and continuing violence in Iraq.
Allen is the sixth Republican incumbent senator defeated in Tuesday's elections.
Webb's victory ended Republican hopes of eking out a 50-50 split with Vice President Dick Cheney wielding tie-breaking authority.
UPDATE, WED, 6:00 AM: Election Day was a big day for Democrats in Indiana and across the nation.
Democrats won a five-to-four edge in Indiana's congressional delegation - helping them win control of the US House for the first time in 12 years.
Indiana House Democrats have knocked off at least four Republican incumbents and regained control of the chamber.
Republican House Speaker Brian Bosma concedes that his party will now trail by at least 51-to-49.
Previously: Democrats have the upper hand in the House and will have a lock if they hold their seats.
They've won 15 Republican-held districts. The winners appear to have ridden a tide of discontent over the Iraq war, President Bush and Capitol Hill scandals.
The wins were spread across the country.
In the conservative Ohio River Valley, Democrats ousted John Hostettler, Chris Chocola and Mike Sodrel in Indiana, and Anne Northup in Kentucky.
In the Northeast, Nancy Johnson in Connecticut and Charles Bass in New Hampshire lost.
In the South, Charles Taylor lost to a former NFL quarterback in North Carolina and Clay Shaw failed to win re-election in Florida.
