President Obama holds an edge over GOP nominee Mitt Romney as voters head to the polls on Election Day, according to the final survey from The Washington Post/ABC News.

The poll, released Monday, shows Obama with 50 percent support among likely voters to 47 for Romney.

In the same poll 10 days back, Romney held a 50-47 edge over the president.

Independents, who 10 days ago backed Romney 58-38, are almost evenly split, with 48 percent now for Romney to 46 for Obama. 

While the race is still close, with other national polls showing the candidates in a dead heat, most voters believe the president will win reelection. Fifty-five percent say Obama will win, to 35 percent for Romney. 

Obama also holds an edge in enthusiasm, with 69 percent of his supporters describing themselves as “very enthusiastic” to 61 percent of Romney backers who say the same.

The president also holds a positive approval rating with 52 percent approval to 46 percent disapproval. But voters say Romney would do better on the economy by 48-47.

Obama holds the edge, 51-43, on which candidate better understands the problems of voters.

A Gallup daily tracking poll Monday gave Romney a 1-point edge at 49-48, while a CNN/ORC poll showed the candidates tied at 49.

A Rasmussen survey released early Tuesday showed Romney up 49-48 over Obama.

The poll, which was conducted from Nov. 1 to 4, has a 2.5 percent margin of error.
