Joe Biden is poor bet for Barack Obama. John McCain now 7/4.

From William Hill:

WILL BARACK RUNNING MATE HELP STOP McCAIN FIGHT BACK?

Despite finally appointing his running mate, Joe Biden - once quoted at 50/1 to get the role by William Hill - Barack Obama is losing ground with punters in the race to the White House.

John McCain has been backed from 2/1 to 7/4 to win the USPresidential Election with William Hill, who have lengthened favourite Barack Obama's odds from 4/11 to 2/5.

'Hillary Clinton was the best backed candidate to run with Obama and had he picked her it would have cost us a substantial five figure payout' said Hill's spokesman Graham Sharpe.
