With just eight days until polling day, Virginia remains finely poised.
A Washington Post poll yesterday put Barack Obama in the lead by 51 per cent to 47 per cent of likely voters, but other recent surveys have shown either a dead heat or a tiny advantage for his Republican rival.
In the past decade, population flows and changing demographics have turned Virginia from a Republican redoubt into a swing state, enabling Obama four years ago to become the first Democrat to carry it in a presidential election since Lyndon Johnson's national landslide in 1964.
This time, both candidates have a plausible roadmap to victory in the state, and its 13 electoral college votes that could determine the outcome.
For the President, the key is to get out the vote in the state's most populated areas - the capital Richmond, southeast Virginia around Hampton and the Norfolk naval base and, above all, the new Virginia of the ever-expanding suburbs of Washington DC - where his edge among black, Hispanic and women voters counts most.
