Mitt Romney is ahead by a single percentage point in Ohio, according to internal polling data provided to MailOnline by a Republican party source.
Internal campaign polling completed last night by campaign pollster Neil Newhouse has Romney three points up in New Hampshire, two points up in Iowa and dead level in Wisconsin and - most startlingly - Pennsylvania.
If the Romney campaign's internal numbers are correct - and nearly all independent pollsters have come up with a picture much more favourable for Obama - then the former Massachusetts governor will almost certainly be elected 45th U.S. President.
Internal polls show Romney trailing in Nevada, reflected in a consensus among senior advisers that Obama will probably win the state. Early voting in Nevada has shown very heavy turnout in the Democratic stronghold of Clark County and union organisation in the state is strong.
(...) The Romney campaign believes that both Florida, Virginia and North Carolina - all of which Obama won in 2008 - are 'done' for the Democratic incumbent, as one senior adviser put it.
