Obama and Romney tied in presidential race, Reuters/Ipsos poll

Republican presidential hopeful Mitt Romney has closed the gap with President Barack Obama with the two candidates now tied in the November 6 presidential race, according to a Reuters/Ipsos daily tracking poll released on Monday.

The online survey of likely voters found Obama and Romney were each supported by 46 percent of the electorate ahead of the third and final debate.

Romney trailed by 1 percentage point when the poll was last published on Saturday.

The two candidates have remained within a marginal three percentage points of each other following their first debate on October 3.

However, Obama still holds an advantage in the swing states that will determine the outcome of the election.

Reuters/Ipsos online polls are measured using a credibility interval. The survey of 957 likely voters, carried out between October 18 and October 22, has a credibility interval of 3.6 percentage points.

Among a larger pool of voters, Obama leads Romney 45 percent to 42 percent.

Early voting is now underway in 49 states and the District of Columbia.

The poll found that 16 percent of registered voters have already cast their ballots.
