WASHINGTON - US President Barack Obama and Republican challenger Mitt Romney remain essentially tied in the race for the White House three days before the November 6 election, according to a Reuters/Ipsos daily tracking poll released on Saturday.
Of likely voters polled nationally, 47 percent said they would back Obama, the Democratic incumbent, while 46 percent said they would back Romney, the former Massachusetts governor.
The results fall within the poll's credibility interval, a tool used to account for statistical variation in Internet-based polls.
The two men have been locked in a tight race for weeks. Both are doing final swings in battleground states over the weekend, trying to sway a small group of remaining undecided voters and to encourage their supporters to get to the polls.
On Friday, Romney spoke to supporters in West Chester, Ohio, saying he was ready to work with Democrats and Republicans to fix America's struggling economy.
President Obama is also back on the road in crucial swing states with just days before the election on November 6.
Although Romney and Obama are almost tied nationally, the president has an edge in key battleground states that could tip the November 6 election in his favor.
Pundits say Romney will need to make a breakthrough in one of these states or another where Obama is heavily favored to win the White House.
