Republican Donald Trump appears to have carved out a wider path to the White House as a number of states including Florida and Ohio are no longer considered likely wins for Democratic rival Hillary Clinton, according to the latest Reuters/Ipsos States of the Nation project.
The project, which combines opinion polls with an analysis of voting patterns under different election scenarios, still shows Clinton would have the best chance of winning the presidency if the November 8 election were held today.
Yet Trump has caught up to her level of support in several states.
Clinton now has an 83 per cent chance of winning the election by an average of 47 votes in the Electoral College, the body that ultimately selects the president.
In late August, it estimated Clinton had a 95 per cent chance of winning by an average of 108 electoral votes.
Over the past few weeks, Clinton's lead in the national polls has slipped considerably.
A separate Reuters/Ipsos poll of likely voters showed an 8-point lead for Clinton has vanished since the last week of August.
Clinton is still favoured to win 17 states, including many with large, urban populations such as New York, New Jersey and California that heavily influence the outcome of the election. Trump would likely win 23 states, many of them with smaller populations.
The number of states projected for Clinton has dropped over the past few weeks. Two of those states, Ohio and Florida, were considered likely wins for Clinton in late August. Now the candidates are about even in support. Five more states, including Michigan and North Carolina, are also up for grabs.
The sample size was insufficient to determine the outcome in Wyoming, Vermont, Alaska and the District of Columbia, though Alaska usually votes Republican and Washington D.C. for the Democratic Party candidate.
The Reuters/Ipsos States of the Nation project is driven by an online survey that gathers responses from about 15,000 people per week.
