A presidential race between incumbent Barack Obama and leading Republican candidate Mitt Romney would end up in a very tight finish, two different polls have said.
A CNN/ORC International Poll said Obama, who is seeking re-election in the November elections, and Romney, the former Governor of Massachusetts, are statistically tied in a hypothetical general election matchup.
In the poll, Obama shows signs of weakness on the economy, while Romney is seen by some as out of touch with ordinary Americans, it said.
Obama is also virtually tied with Ron Paul, another Republican presidential contender, but has a solid lead over Rick Santorum and Newt Gingrich in hypothetical head-to-head matchups.
Santorum and Gingrich are the other two Republican presidential aspirants.
The CNN/ORC International poll said that more respondents think Romney is better suited to get the economy back on track than Obama, 53% to 40%.
The poll was conducted on January 11-12 after Romney won the New Hampshire primary.
In another poll, Fox News said that in a potential Obama-Romney election, 46% of voters would back Obama and 45% Romney if the election were held today.
Obama's narrow advantage is well within the poll's three percentage-point margin of sampling error, the news agency said.
All in all, 51% of voters have a favorable opinion of Obama and 46%t unfavorable.
For Romney, 45% view him favorably and 38%t unfavorably, it said.
The CNN said Obama's approval rating was largely unchanged since mid-December, with 47% now approving of how Obama is handling his job, compared with 49%t a month ago.
"Currently 45% of voters approve and 47% disapprove of the job President Obama is doing. That's little changed from December when 44% approved and 51% disapproved," Fox News said.
