Obama, Romney fight on at the end of long and bitter presidential campaign

WASHINGTON - President Barack Obama and Republican challenger Mitt Romney have closed out their hard-fought and deeply negative battle for the White House, yielding centre stage to voters who face a stark choice on Election Day between fundamentally different visions for the country's future.

After months of campaigning and billions of dollars spent in the battle for leadership of the world's most powerful country, Obama and Romney were in a virtual nationwide tie ahead of Tuesday's election, an overt symptom of the vast partisan divide separating Americans in the early years of the 21st century.

Obama appeared to have a slight edge, however, in some of the key swing states such as Ohio that do not vote reliably Democratic or Republican. That gives him an easier path to reach the 270 electoral votes needed to win the presidency.

Romney decided to make a late dash to Cleveland and Pittsburgh for rallies on Tuesday before returning to his Boston home to await the returns. Obama, who spent Monday night at his home on Chicago's South Side, opted to make a dozen radio and satellite TV interviews from Chicago to swing states to keep his closing arguments fresh in voters' minds.

Romney has made a late-campaign drive for Pennsylvania, a state that had been seen as solidly in the Obama column. The move was widely seen as a push — perhaps against all odds — to compensate for Obama's expected victory in Ohio.

Under the U.S. system, the winner of the presidential election is not determined by the nationwide popular vote but in state-by-state contests. The candidate who wins a state — with Maine and Nebraska the exceptions — is awarded all of that state's electoral votes, which are apportioned based on representation in Congress.

Both sides cast the Election Day choice as one with far-reaching repercussions for a nation still recovering from the biggest economic downturn since the Great Depression and at odds over how big a role government should play in solving the country's problems.

"It's a choice between two different visions for America," Obama declared Monday in Madison, Wisconsin, asking voters to let him complete work on the economic turnaround that began in his first term. "It's a choice between returning to the top-down policies that crashed our economy, or a future that's built on providing opportunity to everybody and growing a strong middle class."

Romney argued that Obama had his chance and blew it.

"The president thinks more government is the answer," he said in Sanford, Florida. "No, Mr. President, more jobs, that's the answer for America."

It wasn't just the presidency at stake Tuesday: All 435 seats in the House of Representatives, a third of the 100 Senate seats, and 11 governorships were on the line, along with state ballot proposals on topics ranging from gay marriage to legalizing marijuana. Democrats were expected to maintain their majority in the Senate, with Republicans doing likewise in the House, raising the prospect of continued partisan wrangling no matter who might be president.

The two candidates and their running mates — Vice-President Joe Biden and Republican Rep. Paul Ryan — stormed through eight battleground states and logged more than 6,000 flight miles (9,600 flight kilometres) Monday on their final full day of campaigning.

Obama's final campaign rally, Monday night in Des Moines, Iowa, was filled with nostalgia as he returned to the state which launched him on the road to the White House in 2008 with a victory in its lead-off caucuses over Hillary Rodham Clinton, now his secretary of state. A single tear streamed down Obama's face during his remarks, though it was hard to tell whether it was from emotion or the bitter cold. The president had campaigned earlier in the day in Wisconsin and Iowa.

Obama, making his last run for office at the still-young age of 51, was tickled to have rocker Bruce Springsteen along as his travelling campaign, telling the crowd in Madison, "I get to fly around with him on the last day that I will ever campaign — so that's not a bad way to end things."

The president urged voters in Iowa to help him finish what they started here four years ago.

"I've come back to Iowa one more time to ask for your vote," Obama told 20,000 supporters at the outdoor rally. "This is where our movement for change began."

After rallies in Florida, Virginia and Ohio, Romney returned Monday night to New Hampshire, where he won the state's first-in-the-nation primary in January, speaking to about 10,000 people at the Verizon Wireless arena.

Romney, 65, assailed Obama's economic policies amid the recession, and promised to bring change that he asserted Obama had only talked about.

"Talk is cheap, but a record is real," Romney said. If elected, Romney would be the first Mormon U.S. president.

The final Washington Post-ABC News tracking poll, released Monday, showed Obama with support from 50 per cent of likely voters to 47 per cent for Romney. The poll had a margin of error of 2.5 percentage points.

Fitting for a tight election, voters in tiny Dixville Notch, New Hampshire, split over the candidates, Obama and Romney receiving five votes each when balloting took place at midnight. In nearby Hart's Location, the hamlet that shares the traditional honour of casting the first presidential ballots on Election Day, Obama won with 23 votes, Romney received nine and Libertarian Gary Johnson received one.

More than 30 million absentee or early ballots have already been cast, including in excess of 3 million in Florida.

Obama and Romney, a former Massachusetts governor and the ultra-wealthy founder of a private equity firm, have spent months highlighting their sharp divisions over the role of government in Americans' lives, in bringing down the stubbornly high unemployment rate, reducing the $1 trillion-plus federal budget deficit and reducing a national debt that has crept above $16 trillion.

The economy has proven a huge drag on Obama's candidacy as he fought to turn it around after the near financial meltdown and deepest recession since the Great Depression of the 1930s, a downturn that was well under way when he replaced George W. Bush in the White House on Jan. 20, 2009.

Obama insists there is no way reduce the staggering debt and safeguard crucial social programs without asking the wealthy to pay their "fair share" in taxes. Romney, who claims his successful business background gives him the expertise to manage the economy, favours lowering taxes and easing regulations on businesses, saying this would spur job growth.

In surveys of the battleground states, Obama held small advantages in Nevada, Ohio, Iowa and Wisconsin — enough to deliver a second term if they held up, but not so significant that they could withstand an Election Day surge by Romney supporters. Romney appears to be performing slightly better than Obama or has pulled even in North Carolina, Virginia and Florida.

The biggest focus has been on Ohio, an industrial state that has gone with the winner of the last 12 presidential elections, which both candidates visited Monday. No Republican has ever won the White House without carrying Ohio.

Both campaigns say the winner will be determined by which campaign is better at getting its supporters to the polls. The president needs the overwhelming support of blacks and Hispanics to counter Romney's big lead among white males.

Romney, who described himself as "severely conservative" during the Republican primary campaign, has shifted sharply in recent weeks to appeal to the political centre, highlighting his claim to have been deeply bipartisan when he was governor of Democratic-leaning Massachusetts.

The forecast for Election Day promised dry weather for much of the country, with rain expected in two battlegrounds, Florida and Wisconsin. But the closing days of the campaign played out against ongoing recovery efforts after Superstorm Sandy. Election officials in New York and New Jersey were scrambling to marshal generators, move voting locations, shuttle storm victims to polling places and take other steps to ensure everyone who wanted to vote could do so.
