Washington (CNN) - The race for the White House remains very close, according to a new national poll, partly because neither President Barack Obama nor Republican challenger Mitt Romney have a clear advantage on issue number one - the economy.
A CNN/ORC International survey released Friday also indicates that Obama supporters are more energized right now than those backing Romney.

According to the poll, 49% of registered voters say that if the November election were held today, they would vote for Obama, while 46% say they would cast a ballot for Romney, the unofficial GOP presidential nominee. The president's three point margin is within the survey's sampling error. Obama had a nine point advantage in CNN's last national poll, which was conducted in early April.
"Which candidate better understands how the economy works? That's a tie as well - 45% pick Obama, 45% choose Romney," says CNN Polling Director Keating Holland.
According to the survey, one in five questioned say neither candidate can fix the economy, with another one in five saying the economy will recover regardless of who wins in November. Among the rest, once again there is no clear advantage - 31% say economic conditions will improve only if Romney wins; 28% think things will get better only if Obama stays in office.
The poll was conducted Tuesday through Thursday, before the release Friday morning of the May unemployment numbers. According to the disappointing report from the Labor Department, the nation's unemployment level edged up to 8.2% last month, with only 69,000 jobs created in May.
According to the poll, the economy, by far, remains issue number one. Fifty-two percent said that it's the most important issue facing the country today. The deficit, at 18% is a distant second.
Over the past few weeks, the Obama campaign has been hammering Romney's business experience at Bain Capital, the private equity firm he co-founded. Did their strategy work?
"The public splits down the middle on Romney's business experience as well," adds Holland. "Fifty percent say that Romney has the right experience to reduce unemployment and improve the economy if he were elected, with 45% saying he does not."
The poll also indicates that Americans' views of the economy haven't gotten any better or worse since the spring. In March, the number who thought the economy was in good shape jumped from 18% to 31%, but there has been no additional movement since then. Sixty-nine percent say economic conditions are poor.
Although the race for the White House is essentially tied, Obama does have one big advantage: His supporters right now are far more enthusiastic about him. More than six in ten Obama voters say they strongly support the president, while only 47% of Romney voters feel that way about their candidate.
Nearly three-quarters of those questioned say they've made up their mind about who they will vote for in November, with one in four saying it's possible they could change their mind.
In the battle for crucial independent voters, the poll indicates Romney holds a 51%-39% advantage.
The president's approval rating continues to hover around the 50% mark. Fifty-two percent give Obama thumbs up on the job he's doing in the White House, with 47% saying they disapprove of how he's handling his duties.
The survey also indicates Americans are divided in the battle for Congress, with 48% saying they would back the Democratic candidate in their congressional district and 45% saying they would support the GOP candidate.
The CNN poll was conducted by ORC International from May 29-31, with 1,009 adults nationwide, including 895 registered voters, questioned by telephone. The survey's overall sampling error is plus or minus three percentage points, with a sampling error of plus or minus 3.5 percentage points for registered voters.
