Voters welcomed an end to the longest, most expensive presidential election on record. "It's the only way to make the ads stop," Amanda Karel, 25, said as she waited to vote at a banquet hall in Columbus, Ohio.

Both sides spent a combined $600 million on TV and radio ads, more than twice the total from 2000.

Bush won among white men, voters with family incomes above $100,000 and weekly churchgoers. Three-fourths of white voters who described themselves as born-again Christians or evangelicals supported Bush.

The president had hoped to increase his support among the religious right since 2000, but exit polls suggest there was little change.

Kerry retained Gore's margins among blacks and union households, key parts of the Democratic base. His voters named the economy and Iraq as top issues.

One in 10 voters were casting ballots for the first time and fewer than 10 percent were young voters, hardly the groundswell that experts had predicted. Kerry was favored by both groups, according to the surveys conducted for The Associated Press by Edison Media Research and Mitofsky International.

Officials predicted a turnout of 117.5 million to 121 million people, the most ever and rivaling the 1960 election in the percentage of eligible voters going to the polls.

Poring over exit polls and field reports, Bush's aides in Arlington, Va., identified low-turnout precincts and dispatched more walkers to them. In Boston, advisers gave Kerry a longer-than-expected list of TV interviews to conduct by satellite to Wisconsin, Minnesota, Colorado, New Mexico, Nevada and Oregon.

Kerry's aides also tried to boost turnout in Hispanic areas by having the candidate's wife, Teresa Heinz Kerry, do Spanish-language television interviews. Exit polls showed the Democrat winning the Hispanic vote, but not by as much as Gore in 2000.

Voters in Wisconsin, Michigan and Ohio received a wave of last-minute telephone calls as Kerry's strategists sought to nail down victories in those key Midwest battlegrounds.

Bush won Alabama, Alaska, Arizona, Arkansas, Colorado, Florida, Georgia, Idaho, Indiana, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Montana, Nebraska, North Carolina, North Dakota, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, West Virginia and Wyoming.

Kerry won California, Connecticut, Delaware, the District of Columbia, Illinois, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington and statewide in Maine. One Maine vote remained a tossup.

Only nine of 34 Senate races on the ballot appeared competitive. One of them was held by Senate Minority Leader Tom Daschle, who was in a pitched fight against Republican John Thune.

All 435 House seats were up for election, but Democrats had little hope of a takeover. Republicans hold 227 seats, Democrats 205, with one Democratic-leaning independent and two vacancies in Republican-held seats.

Eleven gubernatorial contests were being decided Tuesday, along with 5,800 legislative seats in 44 states. Former Bush administration budget director Mitch Daniels won the governorship in Indiana, taking the seat from the Democrats.

Among the notable ballot measures, voters in 11 states approved propositions that would ban gay marriage. In California, voters approved spending $3 billion on stem-cell research.
