Record turnout looks to send Obama to White House

US voters queued for hours today at the end of a marathon and historic political race expected to make Democrat Barack Obama the country’s first black president.

It seemed only a huge come-from-behind upset by Republican John McCain could overturn the predictions of a President Obama.

A record number of voters turned out in an election that stood to change the political face of a nation burdened with its worst economic crisis in nearly 80 years and still fighting wars in Iraq and Afghanistan.

The economy was by far the top issue on voters’ minds.

An Associated Press exit poll found six in 10 across the United States named the economy as the most important issue facing the country. None of four other issues on the list – energy, Iraq, terror or health care – was chosen by more than one in 10.

Early figures showed the state of Indiana was a toss-up and Mr Obama held a lead in Virginia. Neither state has voted for a Democratic presidential candidate since 1964.

A victory for the first-term Illinois senator would appear nearly certain should he hold reliably Democratic Pennsylvania and pick off either Ohio or Florida, both of which gave their huge 47-electoral vote prizes to President George Bush in 2000 and 2004.

Most pre-vote polling of the states showed Obama near or already above the 270 electoral votes needed for victory.

An estimated 153 million voters were eligible, and in an indication of interest in the battle for the White House, about 40 million already had voted as election day dawned. Turnout was heavy. In Virginia, for example, officials estimated nearly 75% of eligible voters would cast ballots.

Mr Obama was on the verge of stepping through a door opened 145 years ago when Abraham Lincoln, a fellow Illinois politician, issued the Emancipation Proclamation that freed African-Americans from enslavement in the rebellious South in the midst of a wrenching civil war.

The senator would be laying claim to the White House on January 20, only 43 years after the country enacted a law that banned the disenfranchisement of blacks in many Southern states where poll taxes and literacy tests were common at the time.

Mr Obama clambered out of political obscurity four years ago with a stunning speech at the Democratic National Convention as he was running a successful campaign to become a US senator from Illinois.

He was awaiting the results at home in Chicago after a marathon campaign across 21 months and 49 states. At 47, with only four years in the Senate, he sought election as one of the youngest presidents, and one of the least experienced in national political affairs.

That was not what set the Illinois senator apart, though. As a black man, he confronted a previously unbreakable barrier as he campaigned on twin themes of change and hope in uncertain times.

Mr McCain, a generation older than his rival at 72, waited in Arizona to learn the outcome of the election. It was his second try for the White House, following his defeat in the battle for the Republican nomination in 2000.

A conservative, he ran seeking to stress his maverick streak. And a Republican, he did what he could to separate himself from an unpopular President Bush.

For the most part, the two presidential candidates and their running mates, Sarah Palin Joe Biden, spent weeks campaigning in states that went for Mr Bush four years ago. Virginia, Florida, North Carolina, Ohio, Iowa, Colorado, New Mexico and Nevada drew most of their time. Pennsylvania also drew attention as McCain sought to invade traditionally Democratic turf.

While the Iraq war dominated the campaign early in the year, it had long since faded as an issue as voters cast ballots.

The race was easily the costliest in history, in excess of $1bn, more after the congressional campaigns were counted.

Figures through mid-October showed Mr Obama had spent roughly $240m on television and radio advertisements.

Mr McCain had spent about $115m and the Republican National Committee another $80m on his behalf.
