Obama Surges Ahead in Florida

A worldwide economic crisis can make a lot of difference to a voter. Or at least it has done to Isabelle Murawski. For the past two elections, the pensioner has reliably voted for George W Bush, casting her ballot in Florida's Broward County, one of the epicentres of the voting debacle that saw Bush win the White House in 2000.

But now Murawski is going to vote for Barack Obama. 'I am supporting Obama, I think,' she said, while strolling in Florida's warm sunshine in the coastal resort town of Hollywood. 'It's the economy first and foremost. Everyone I know is worried about their pensions.'

Murawski is not alone in switching sides in Florida. In the past few weeks the polls in this vital southern swing state have taken a remarkable turn. After long months of the Republican candidate John McCain being comfortably ahead, Obama has suddenly surged forward. Four recent polls have put Obama between four and eight points ahead in Florida. It is a hugely significant development. McCain almost certainly cannot win the keys of the White House without Florida's 27 precious electoral college votes. 'There is clearly something going on. There has been a solid swing to Obama,' said Professor Lance DeHaven-Smith, who is a political scientist at Florida State University.

The development mirrors a trend nationwide. In the face of the economic disaster gripping America, the presidential race has undergone yet another about-face. Voters have broken narrowly but firmly for Obama, and McCain has seen his support wither in the face of the crisis. Polls consistently show Obama with a solid four or five-point lead. Previously long-shot Republican states like North Carolina, Georgia and Virginia have suddenly become Democratic possibilities. In the meantime, McCain's campaign has decided to pull out of Michigan, writing off the state in favour of easier targets.

But it is Florida that all eyes have now turned to. An Obama victory there would virtually assure that America gets its first ever black President. It would also go some way to purging the dreadful scars still lingering in the Democratic psyche after the disputed 2000 election result. No Democrat can ever forget the saga of the hanging chads - the spoiled ballot papers that led to a protracted recount and a United States Supreme Court ruling which ensured that Bush won both Florida and the White House.

Now eight years of Republican rule could end in the very same state where they began. 'I think a lot of Democrats in Florida would finally feel vindicated,' said DeHaven-Smith.

The key to winning in Florida is a 132-mile stretch of busy road known as Interstate 4, or I-4. The road cuts across the heart of the state, stretching from Tampa Bay to Daytona Beach. It is both the literal and metaphorical middle ground of Florida politics. It bridges the gap between the Republican core of northern Florida, which is very much a part of the conservative Deep South, and the large Democrat-leaning cities of the south-east, such as Miami and Fort Lauderdale.

This so-called 'I-4 corridor' is home to most of Florida's independent voters and is some of the hardest contested political turf in the whole of America. At its heart is the sprawling city of Orlando and the fierce battle that is being waged there seems to be being won by Obama. Certainly Terrence Golden, a kitchen manager at an Orlando restaurant, is backing Obama. He is one of the hundreds of thousands of transplants to the I-4 corridor who have come south seeking jobs and sunshine and was in no doubt as to where his vote was going. 'McCain is more of the same - just look at all the mess they have created already. We need a change,' he said.

Obama is hoping to capitalise on a lot more voters like Golden. So far, the effort has gone well. His campaign has spent vast amounts of cash in Florida and set up a large organisation to register new voters, especially among blacks and students. It has 350 paid staff in the state, compared with 70 working for McCain. It has outspent its rival by $8m. Obama's political ads have saturated the airwaves and surrogate campaigners, such as Bill and Hillary Clinton and General Wesley Clark, have regularly been on the stump, along with Obama himself.
