From the BBC news website:
"Interim results give President Bush a clear lead of almost 137,000 votes, with at least 146,000 provisional ballots awaiting verification.
That process, which is expected to last for days, will begin at noon (1700 GMT) on Thursday.
However long it takes, Mr Kerry will have to win virtually every single conditional ballot that is allowed, in order to carry Ohio and with it the presidency.
So while it is mathematically possible, it looks like a forlorn hope."
