Obama trails McCain in the polls as Hillary's supporters switch sides
Updated on 20 August 2008
A new survey shows Barack Obama trailing John McCain by five points, fuelling fears that his campaign is losing momentum.
For months he's maintained a steady but narrow lead against the Republican in the polls, but now there are fears his supporters may be dropping off.
Among his detractors are many of Hillary Clinton's supporters, mainly women, who believe Clinton was the victim of a sexist campaign to deny her the nomination.
Some have now set up an organisation to rally supporters to McCain.
