Clinton barely edging Trump

Hillary Clinton is in a close race with Donald Trump in a new national poll released the weekend before Election Day.

Clinton leads 45% to 43% in a Fox News survey, within the poll's margin of error. Libertarian Gary Johnson earns 5% and Green Party nominee Jill Stein takes 2%.

That's in line with other polls this week, which show Clinton leading by just a few percentage points, a smaller lead than the one she held before the FBI announced it was looking at newly discovered emails potentially related to her private email server.

Combined with the other four most recent national polls, Clinton enjoys a 5% lead entering the final hours of the campaign. CNN's Poll of Polls shows her at 47%, Trump at 42%, Johnson with 4% and Stein with 2%.

The Fox poll of 1,107 likely voters was fielded November 1 to November 3 and has a sampling error of 3 percentage points.

A Reuters/Ipsos tracking poll released on Friday conducted from Oct. 30-Nov. 3 showed that 44 percent of likely voters in Tuesday's election support Clinton while 39 percent support Trump.

Real Clear Politics, which averages together most national polls, estimates that Clinton's lead has dropped from 5 points at the end of last week to less than 2 points on Friday.

This is similar to 2012, when the Reuters/Ipsos tracking poll showed President Barack Obama with a 3 to 7 point advantage over Republican challenger Mitt Romney in the final days of the campaign while Real Clear Politics showed Obama's lead nearly vanishing ahead of the election. Obama was re-elected with a 4-point advantage in the popular vote.

Clinton, despite her national lead, appears to have lost ground in a number of states, according to a separate polling effort that takes a more granular look at the race.

The Reuters/Ipsos States of the Nation project shows races in Florida, North Carolina and Michigan have tilted away from Clinton over the past week and are now considered too close to call. These swing states are hotly contested because their voters can swing either to Republicans or Democrats and can be decisive in presidential elections.

The Poll of Polls, which does not have a sampling error, includes the Fox poll; the ABC News/Washington Post poll conducted October 31-November 3; the CBS News/New York Times poll conducted October 29-November 1; the Suffolk University/USA Today poll conducted October 20-24 and the CNN/ORC poll conducted October 20-23.
