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.
Internal poll 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.
Romney is to campaign in Cleveland, Ohio and Pittsburgh, Pennsylvania on election day, reflecting the tightness of the race in Ohio and the tantalising prospect of success in Pennsylvania, which has not gone Republican in a presidential campaign for 24 years.
