WASHINGTON, Nov. 8 (AP)--After a night of suspense and drama, the presidential vote is cast but the verdict is unknown.

The outcome of the race between Republican George W. Bush and Democrat Al Gore hung on an incomplete vote count Wednesday in Florida, where only a few thousand votes separated the two candidates out of 95 million cast across America.

The outcome--or lack of one--left the nation wondering who would succeed Bill Clinton on Jan. 20 and raised the prospect that the question would be unanswered for days.

Gore himself thought he had lost when the broadcast networks projected Bush the winner in Florida--and thus the nation.

The vice president telephoned his congratulations to the Texas governor.

Then he called again and took his concession back.

"There's never been a night like this one," Gore campaign chairman William Daley said at Gore headquarters in Nashville, Tenn. "This race is simply too close to call."

Standing in the rain, the Nashville crowd chanted, "Recount!"

The Associated Press count showed Bush leading by less than 1,700 votes in Florida, and both the Bush and Gore campaigns were sending teams of lawyers to the state Wednesday to keep an eye on the recount. A formal canvass of the Florida ballots could take 10 days.

The election stacked up as the closest race since John F. Kennedy defeated Richard M. Nixon in 1960 by 118,574 votes, a contest whose outcome was also uncertain until the day after the voting.

Bush and Gore were both in reach of the 270 electoral votes needed to win the presidency. As dawn broke in the East, Bush has won 29 states for 246 electoral votes. Gore has won 18 states plus the District of Columbia for 255.

Green Party insurgent Ralph Nader failed to get enough votes to qualify for federal funding in 2004, but he took enough--presumably from Gore--to emerge as the potential spoiler to the vice president.

The congressional race was narrow as well. Before the election, Congress was Republican but closely divided, and it emerged Republican and even more closely divided following Tuesday's voting.

Republicans picked up six Democratic House seats in scattered states, enough to renew their hold for two more years. But their majority shrank when they gave back eight other seats elsewhere, including four in California.

"We figured it was going to be close," said House Speaker Dennis Hastert, R-Ill.--and it was.

With winners declared in 33 of the 34 races at stake, Republicans will have at least a 50-48 margin in the Senate. Too close to call was the race in Washington state, where former Rep. Maria Cantwell was challenging incumbent Republican Sen. Slade Gorton.

Voters ousted Sen. William V. Roth of Delaware, chairman of the Senate Finance Committee and father of the tax-saving Roth IRA, as well as four Republicans and Democrat Chuck Robb of Virginia

Missourians rejected Republican Sen. John Ashcroft, electing instead their dead governor, Mel Carnahan, killed three weeks ago in a plane crash. His successor has pledged to appoint widow Jean Carnahan, who told supporters, "I pledge to you, rather, let's pledge to each other, never let the fire go out."

In New York, Hillary Rodham Clinton became the first president's wife to win a Senate seat. When word of his wife's victory came in, President Clinton was on the telephone in their hotel suite, talking to a personality named Billy T on Las Vegas radio station KCEP, trying to nudge Westerners to the polls.

Clinton told Billy T he was the first president in history to have a wife in the Senate, "and I like it."

Across the nation, with 98 percent of the votes counted, Bush and running mate Dick Cheney had 48 percent to 48 percent for Gore and his running mate, Joseph Lieberman, who was bidding to become the first Jewish vice president. The Gore-Lieberman ticket held a slim lead in the popular vote.

Regardless of the outcome of the presidential race, Lieberman was guaranteed a job next year. He easily won re-election to the Senate from his home state of Connecticut. If the Democrats win the White House, he would be replaced by a Republican appointed by the state's GOP governor.

Bush, whose father, President George H.W. Bush, was defeated by Clinton in 1992, had the satisfaction of carrying both Clinton's and Gore's home states of Arkansas and Tennessee.

Bush, in Austin, Texas, ate dinner and said he was worried more about what the suspense was doing to his parents than to himself. He did not address his supporters, who waited deep into the night in a cold rain.

And Gore, aides said, went to bed.

Voter turnout was higher than expected, a notch above 1996, when fewer than half of the adult population cast ballots.

On Tuesday, between 52 percent and 53 percent voted, estimated one turnout expert, Curtis Gans, director of the Committee for the Study of the American Electorate.
